Therefore, GCD of numbers 777, 987, 89, 836 is 1

Given Input Data is 777, 987, 89, 836

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

Prime Factorization of 777 is 3 x 7 x 37

Prime Factorization of 987 is 3 x 7 x 47

Prime Factorization of 89 is 89

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

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(777, 987) = 36519

GCD(777, 987) = ( 777 x 987 ) / 36519

GCD(777, 987) = 766899 / 36519

GCD(777, 987) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 89

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

LCM(21, 89) = 1869

GCD(21, 89) = ( 21 x 89 ) / 1869

GCD(21, 89) = 1869 / 1869

GCD(21, 89) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 836

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

LCM(1, 836) = 836

GCD(1, 836) = ( 1 x 836 ) / 836

GCD(1, 836) = 836 / 836

GCD(1, 836) = 1

GCD of 777, 987, 89, 836 is 1
