Therefore, GCD of numbers 771, 836, 661 is 1

Given Input Data is 771, 836, 661

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

Prime Factorization of 771 is 3 x 257

Prime Factorization of 836 is 2 x 2 x 11 x 19

Prime Factorization of 661 is 661

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(771, 836) = 644556

GCD(771, 836) = ( 771 x 836 ) / 644556

GCD(771, 836) = 644556 / 644556

GCD(771, 836) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 661

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

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

GCD(1, 661) = 661 / 661

GCD(1, 661) = 1

GCD of 771, 836, 661 is 1
