Therefore, GCD of numbers 610, 640, 977, 154 is 1

Given Input Data is 610, 640, 977, 154

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

Prime Factorization of 610 is 2 x 5 x 61

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 977 is 977

Prime Factorization of 154 is 2 x 7 x 11

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(610, 640) = 39040

GCD(610, 640) = ( 610 x 640 ) / 39040

GCD(610, 640) = 390400 / 39040

GCD(610, 640) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 977

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

LCM(10, 977) = 9770

GCD(10, 977) = ( 10 x 977 ) / 9770

GCD(10, 977) = 9770 / 9770

GCD(10, 977) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 154

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

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

GCD(1, 154) = 154 / 154

GCD(1, 154) = 1

GCD of 610, 640, 977, 154 is 1
