Therefore, GCD of numbers 627, 649, 91, 836 is 1

Given Input Data is 627, 649, 91, 836

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

Prime Factorization of 627 is 3 x 11 x 19

Prime Factorization of 649 is 11 x 59

Prime Factorization of 91 is 7 x 13

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(627, 649) = 36993

GCD(627, 649) = ( 627 x 649 ) / 36993

GCD(627, 649) = 406923 / 36993

GCD(627, 649) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 91

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

LCM(11, 91) = 1001

GCD(11, 91) = ( 11 x 91 ) / 1001

GCD(11, 91) = 1001 / 1001

GCD(11, 91) = 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 627, 649, 91, 836 is 1
