Given numbers are 521, 198, 228, 640

The list of prime factors of all numbers are

Prime factors of 521 are 521

Prime factors of 198 are 2 x 3 x 3 x 11

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

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 521, 198, 228, 640

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

Apply this formula for all numbers.

Step1:

LCM(521, 198) = 103158

GCD(521, 198) = ( 521 x 198 ) / 103158

= 521 / 198

= 521

Step2:

LCM(1, 228) = 228

GCD(1, 228) = ( 1 x 228 ) / 228

= 1 / 228

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 521, 198, 228, 640 is 1
