Therefore, GCD of numbers 531, 177, 26, 280 is 1

Given Input Data is 531, 177, 26, 280

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

Prime Factorization of 531 is 3 x 3 x 59

Prime Factorization of 177 is 3 x 59

Prime Factorization of 26 is 2 x 13

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

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(531, 177) = 531

GCD(531, 177) = ( 531 x 177 ) / 531

GCD(531, 177) = 93987 / 531

GCD(531, 177) = 177

Step2:

Here we consider the GCD from the above i.e. 177 as first number and the next as 26

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

LCM(177, 26) = 4602

GCD(177, 26) = ( 177 x 26 ) / 4602

GCD(177, 26) = 4602 / 4602

GCD(177, 26) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 280

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

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

GCD(1, 280) = 280 / 280

GCD(1, 280) = 1

GCD of 531, 177, 26, 280 is 1
