Therefore, GCD of numbers 871, 660, 860 is 1

Given Input Data is 871, 660, 860

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 871 is 13 x 67

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 860 is 2 x 2 x 5 x 43

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(871, 660) = 574860

GCD(871, 660) = ( 871 x 660 ) / 574860

GCD(871, 660) = 574860 / 574860

GCD(871, 660) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 860

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

GCD(1, 860) = 860 / 860

GCD(1, 860) = 1

GCD of 871, 660, 860 is 1
