Given numbers are 628, 220, 360, 457

The list of prime factors of all numbers are

Prime factors of 628 are 2 x 2 x 157

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 457 are 457

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

Given numbers are 628, 220, 360, 457

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

Apply this formula for all numbers.

Step1:

LCM(628, 220) = 34540

GCD(628, 220) = ( 628 x 220 ) / 34540

= 628 / 220

= 628

Step2:

LCM(4, 360) = 360

GCD(4, 360) = ( 4 x 360 ) / 360

= 4 / 360

= 4

Step3:

LCM(4, 457) = 1828

GCD(4, 457) = ( 4 x 457 ) / 1828

= 4 / 457

= 4

So, Greatest Common Divisor of 628, 220, 360, 457 is 1
