Therefore, GCD of numbers 424, 688, 81, 925 is 1

Given Input Data is 424, 688, 81, 925

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

Prime Factorization of 424 is 2 x 2 x 2 x 53

Prime Factorization of 688 is 2 x 2 x 2 x 2 x 43

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 925 is 5 x 5 x 37

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(424, 688) = 36464

GCD(424, 688) = ( 424 x 688 ) / 36464

GCD(424, 688) = 291712 / 36464

GCD(424, 688) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 81

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

LCM(8, 81) = 648

GCD(8, 81) = ( 8 x 81 ) / 648

GCD(8, 81) = 648 / 648

GCD(8, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 925

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

LCM(1, 925) = 925

GCD(1, 925) = ( 1 x 925 ) / 925

GCD(1, 925) = 925 / 925

GCD(1, 925) = 1

GCD of 424, 688, 81, 925 is 1
