Given numbers are 220, 637, 255, 238

The list of prime factors of all numbers are

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

Prime factors of 637 are 7 x 7 x 13

Prime factors of 255 are 3 x 5 x 17

Prime factors of 238 are 2 x 7 x 17

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

Given numbers are 220, 637, 255, 238

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

Apply this formula for all numbers.

Step1:

LCM(220, 637) = 140140

GCD(220, 637) = ( 220 x 637 ) / 140140

= 220 / 637

= 220

Step2:

LCM(1, 255) = 255

GCD(1, 255) = ( 1 x 255 ) / 255

= 1 / 255

= 1

Step3:

LCM(1, 238) = 238

GCD(1, 238) = ( 1 x 238 ) / 238

= 1 / 238

= 1

So, Greatest Common Divisor of 220, 637, 255, 238 is 1
