Given numbers are 515, 228, 561, 634

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 561 are 3 x 11 x 17

Prime factors of 634 are 2 x 317

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 515, 228, 561, 634

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(515, 228) = 117420

GCD(515, 228) = ( 515 x 228 ) / 117420

= 515 / 228

= 515

Step2:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 515, 228, 561, 634 is 1
