Given numbers are 747, 646, 810, 251

The list of prime factors of all numbers are

Prime factors of 747 are 3 x 3 x 83

Prime factors of 646 are 2 x 17 x 19

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 251 are 251

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

Given numbers are 747, 646, 810, 251

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

Apply this formula for all numbers.

Step1:

LCM(747, 646) = 482562

GCD(747, 646) = ( 747 x 646 ) / 482562

= 747 / 646

= 747

Step2:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

Step3:

LCM(1, 251) = 251

GCD(1, 251) = ( 1 x 251 ) / 251

= 1 / 251

= 1

So, Greatest Common Divisor of 747, 646, 810, 251 is 1
