least common prime factor

least common prime factor

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 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


we see that the factor of 4 and 16

4 has factored only 2

16 has factors also only 2


we see that the common p factor 4 and 16 is 2


We divide these number 4 and 16 from factor by 2 processes again and again by prime factor 2.


We fined the least common factor (L. C. M) of 15 and 21 by using the prime factor method.
