Given numbers are 251, 882, 420, 474

The list of prime factors of all numbers are

Prime factors of 251 are 251

Prime factors of 882 are 2 x 3 x 3 x 7 x 7

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 474 are 2 x 3 x 79

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

Given numbers are 251, 882, 420, 474

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

Apply this formula for all numbers.

Step1:

LCM(251, 882) = 221382

GCD(251, 882) = ( 251 x 882 ) / 221382

= 251 / 882

= 251

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 474) = 474

GCD(1, 474) = ( 1 x 474 ) / 474

= 1 / 474

= 1

So, Greatest Common Divisor of 251, 882, 420, 474 is 1
