Given numbers are 690, 625, 687, 798

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 625 are 5 x 5 x 5 x 5

Prime factors of 687 are 3 x 229

Prime factors of 798 are 2 x 3 x 7 x 19

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

Given numbers are 690, 625, 687, 798

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

Apply this formula for all numbers.

Step1:

LCM(690, 625) = 86250

GCD(690, 625) = ( 690 x 625 ) / 86250

= 690 / 625

= 690

Step2:

LCM(5, 687) = 3435

GCD(5, 687) = ( 5 x 687 ) / 3435

= 5 / 687

= 5

Step3:

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

= 1 / 798

= 1

So, Greatest Common Divisor of 690, 625, 687, 798 is 1
