Given numbers are 790, 817, 651, 180

The list of prime factors of all numbers are

Prime factors of 790 are 2 x 5 x 79

Prime factors of 817 are 19 x 43

Prime factors of 651 are 3 x 7 x 31

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

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

Given numbers are 790, 817, 651, 180

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

Apply this formula for all numbers.

Step1:

LCM(790, 817) = 645430

GCD(790, 817) = ( 790 x 817 ) / 645430

= 790 / 817

= 790

Step2:

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

= 1 / 651

= 1

Step3:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

So, Greatest Common Divisor of 790, 817, 651, 180 is 1
