Given numbers are 477, 418, 228, 644

The list of prime factors of all numbers are

Prime factors of 477 are 3 x 3 x 53

Prime factors of 418 are 2 x 11 x 19

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

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 477, 418, 228, 644

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

Apply this formula for all numbers.

Step1:

LCM(477, 418) = 199386

GCD(477, 418) = ( 477 x 418 ) / 199386

= 477 / 418

= 477

Step2:

LCM(1, 228) = 228

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

= 1 / 228

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 477, 418, 228, 644 is 1
