Given numbers are 642, 302, 250, 221

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 302 are 2 x 151

Prime factors of 250 are 2 x 5 x 5 x 5

Prime factors of 221 are 13 x 17

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

Given numbers are 642, 302, 250, 221

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

Apply this formula for all numbers.

Step1:

LCM(642, 302) = 96942

GCD(642, 302) = ( 642 x 302 ) / 96942

= 642 / 302

= 642

Step2:

LCM(2, 250) = 250

GCD(2, 250) = ( 2 x 250 ) / 250

= 2 / 250

= 2

Step3:

LCM(2, 221) = 442

GCD(2, 221) = ( 2 x 221 ) / 442

= 2 / 221

= 2

So, Greatest Common Divisor of 642, 302, 250, 221 is 1
