Therefore, GCD of numbers 63, 917, 127, 255 is 1

Given Input Data is 63, 917, 127, 255

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

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 917 is 7 x 131

Prime Factorization of 127 is 127

Prime Factorization of 255 is 3 x 5 x 17

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(63, 917) = 8253

GCD(63, 917) = ( 63 x 917 ) / 8253

GCD(63, 917) = 57771 / 8253

GCD(63, 917) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 127

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

LCM(7, 127) = 889

GCD(7, 127) = ( 7 x 127 ) / 889

GCD(7, 127) = 889 / 889

GCD(7, 127) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 255

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

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

GCD(1, 255) = 255 / 255

GCD(1, 255) = 1

GCD of 63, 917, 127, 255 is 1
