Least common factor prime means two or more number divided the common number such that 4 and 16 we have the smallest prime number 2 which divided the number 4 and 16 at the same time.
After dividing the number 4 and 16 by prime common factor 2.and saver number 2 and 8.
Then again we divide 2 and 8 by same number 2.and saver number is 1 and 4 other we cannot divide the common factor.
Then the resulting least common prime factor of 4 and 16. Is 2 ×2 = 4
FIRST:
First we take the factor 4 and 16 then we see the prime factor of 4 and 16
4 has factors 1,2,4
16 has factors 1,2,4,8,16
SECOND:
we see that the factor of 4 and 16
4 has factored only 2
16 has factors also only 2
THIRD:
we see that the common p factor 4 and 16 is 2
FOURTH:
We divide these number 4 and 16 from factor by 2 processes again and again by prime factor 2.
FOR EXAMPLE:
We fined the least common factor (L. C. M) of 15 and 21 by using the prime factor method.
