Therefore, GCD of numbers 610, 640, 64, 863 is 1

Given Input Data is 610, 640, 64, 863

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 64 is 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 863 is 863

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 64

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

LCM(10, 64) = 320

GCD(10, 64) = ( 10 x 64 ) / 320

GCD(10, 64) = 640 / 320

GCD(10, 64) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 863

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

LCM(2, 863) = 1726

GCD(2, 863) = ( 2 x 863 ) / 1726

GCD(2, 863) = 1726 / 1726

GCD(2, 863) = 1

GCD of 610, 640, 64, 863 is 1
