Therefore, GCD of numbers 751, 639, 767, 136 is 1

Given Input Data is 751, 639, 767, 136

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

Prime Factorization of 751 is 751

Prime Factorization of 639 is 3 x 3 x 71

Prime Factorization of 767 is 13 x 59

Prime Factorization of 136 is 2 x 2 x 2 x 17

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(751, 639) = 479889

GCD(751, 639) = ( 751 x 639 ) / 479889

GCD(751, 639) = 479889 / 479889

GCD(751, 639) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 767

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

LCM(1, 767) = 767

GCD(1, 767) = ( 1 x 767 ) / 767

GCD(1, 767) = 767 / 767

GCD(1, 767) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 136

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

LCM(1, 136) = 136

GCD(1, 136) = ( 1 x 136 ) / 136

GCD(1, 136) = 136 / 136

GCD(1, 136) = 1

GCD of 751, 639, 767, 136 is 1
