Given numbers are 251, 815, 267, 648

The list of prime factors of all numbers are

Prime factors of 251 are 251

Prime factors of 815 are 5 x 163

Prime factors of 267 are 3 x 89

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 251, 815, 267, 648

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

Apply this formula for all numbers.

Step1:

LCM(251, 815) = 204565

GCD(251, 815) = ( 251 x 815 ) / 204565

= 251 / 815

= 251

Step2:

LCM(1, 267) = 267

GCD(1, 267) = ( 1 x 267 ) / 267

= 1 / 267

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 251, 815, 267, 648 is 1
