Therefore, GCD of numbers 728, 956, 975, 678 is 1

Given Input Data is 728, 956, 975, 678

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

Prime Factorization of 728 is 2 x 2 x 2 x 7 x 13

Prime Factorization of 956 is 2 x 2 x 239

Prime Factorization of 975 is 3 x 5 x 5 x 13

Prime Factorization of 678 is 2 x 3 x 113

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(728, 956) = 173992

GCD(728, 956) = ( 728 x 956 ) / 173992

GCD(728, 956) = 695968 / 173992

GCD(728, 956) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 975

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

LCM(4, 975) = 3900

GCD(4, 975) = ( 4 x 975 ) / 3900

GCD(4, 975) = 3900 / 3900

GCD(4, 975) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 678

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

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

GCD(1, 678) = 678 / 678

GCD(1, 678) = 1

GCD of 728, 956, 975, 678 is 1
