HIGHEST COMMON FACTOR (H. C. F.)​

Answer 1

Answer:

To find highest common factor by using division method is discussed here.

Finding highest common factor (H.C.F) by prime factorization for large number is not very convenient. The method of long division is more useful for large numbers.

In this method we first divide the greater number by the smaller number. The remainder becomes the new divisor and the previous divisor as the new dividend. We continue the process until we get 0 remainder.

We use the repeated division method for finding highest common factor (H.C.F) of two or more numbers.
