00:00hi kids today we will learn what are factors and multiples so let's get
00:08started factors when we multiply two or more numbers we get a product each
00:20number is called a factor of the product example four multiplied by five
00:28multiplied by two equals 40 so here 4 5 & 2 are factors of 40 a number is said
00:43to be the factor of another if it can divide the other number completely here
00:514 5 & 2 can divide 40 completely that is no remainder will be left if we divide
01:0240 with 4 5 & 2 let's have a look at more examples 4 multiplied by 5 equals
01:1520 so here 4 & 5 are factors of 20 4 & 5 can divide 20 completely that is no
01:29remainder will be left 6 multiplied by 3 multiplied by 1 equals 18 so here 6 3 1
01:45are factors of 18 or 6 3 & 1 can completely divide 18 no remainder will
02:00be left to multiply by 3 multiplied by 5 multiplied by 1 equals 30 so 2 3 5 & 1
02:15are factors of 30 and 2 3 5 & 1 can divide 30 completely that is no
02:28remainder will be left kids one is the factor of every number because one can
02:38any number or every number now let's learn what are multiples multiples of a
02:49number are numbers that comes in its table or numbers that results after
02:57multiplying the number with any number like 2 multiplied by 0 equals 0 2
03:09multiplied by 1 equals 2 2 multiplied by 2 equals 4 2 multiplied by 3 equals 6
03:24here 0 2 4 & 6 are multiples of 2 there is no end to the number of multiples of
03:35a number 0 and number itself are multiples of every number 2 multiplied
03:47by 0 equals 0 so 0 is multiple of 2 2 multiplied by 1 equals 2 so 2 is a
04:02multiple of 2 similarly 15 multiplied by 0 equals 0 so 0 is multiple of 15
04:1815 multiplied by 1 equals 15 so 15 is multiple of 15 so 0 and the number
04:32itself are multiples of every number the number of multiples of a number are
04:39infinite also remember every number is a multiple of 1 or every number comes
04:49in the table of 1 like 1 multiplied by 4 is 4 so 4 is multiple of 1 1 multiplied
05:06by 13 is 13 so 13 is a multiple of 1 1 multiplied by 67 is 67 so 67 is a
05:23multiple of 1 so every number each and every number is a multiple of 1 now we
05:33know what are factors and multiples now let's answer a few questions what are
05:43the first five multiples of 5 other than 0 let's answer 5 10 15 20 and 25 are the
05:59five multiples of 5 other than 0 which of the following are multiples of 3 we
06:09know 0 and number itself are always multiples of a number so 0 and 3 are
06:19multiples of 3 9 comes in a table of 3 so 9 is a multiple of 3 4 does not come
06:32in the table of 3 so it's not a multiple of 3 20 also does not come in the table
06:41of 3 12 comes in the table of 3 so it's a multiple of 3 15 2 comes in the table
06:53of 3 so 15 also is a multiple of 3 so 3 9 0 12 and 15 are multiples of 3 now
07:10write all the factors of 6 first of all 1 and the number itself are factors of
07:21every number so 1 6 are factors of 6 next 2 can divide 6 completely 3 can
07:36divide 6 completely 1 2 3 and 6 are the factors of 6 now which is the greatest
07:48factor of 15 other than the number itself we know that 1 and the number
07:57itself are the factors of a number and the number itself are the biggest factor
08:05now to find the factor which is biggest but other than the number itself let's
08:12find out all the factors of 15 starting from the smallest number 1 is the factor
08:232 cannot divide 15 so 2 is not a factor 3 yes 3 can divide 15 completely so 3 is
08:38a factor 4 cannot 5 yes 5 can divide 15 completely so 5 is a factor of
08:5315 6 cannot 7 cannot 8 cannot so no other number up to 14 can divide 15
09:11completely so we got 1 3 5 and 15 are the factors of 15 out of which 5 is the
09:25biggest factor of 15 other than the number itself so kids what have we
09:33learned factors of a number are numbers that can divide a number completely 1 2
09:445 10 20 can divide 20 completely so all these numbers are factors of 21 and the
09:58number itself are factors of each number and multiples of a number are
10:06the numbers that comes in its table or numbers that results from multiplying
10:13the number with any number like 2 multiplied by 0 is 0 2 multiplied by 1
10:24is 2 2 multiplied by 2 equals 4 2 multiplied by 10 equals 20 here 0 2 4 and
10:4220 are multiples of 2 there is no end to the number of multiples of a number and
10:510 and the number itself are multiples of every number now you may go ahead and
11:00take a quiz to learn more bye-bye
