Therefore, GCD of numbers 965, 640, 70, 653 is 1

Given Input Data is 965, 640, 70, 653

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

Prime Factorization of 965 is 5 x 193

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

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 653 is 653

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(965, 640) = 123520

GCD(965, 640) = ( 965 x 640 ) / 123520

GCD(965, 640) = 617600 / 123520

GCD(965, 640) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 70

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

LCM(5, 70) = 70

GCD(5, 70) = ( 5 x 70 ) / 70

GCD(5, 70) = 350 / 70

GCD(5, 70) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 653

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

LCM(5, 653) = 3265

GCD(5, 653) = ( 5 x 653 ) / 3265

GCD(5, 653) = 3265 / 3265

GCD(5, 653) = 1

GCD of 965, 640, 70, 653 is 1
