Given numbers are 687, 530, 257, 762

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 530 are 2 x 5 x 53

Prime factors of 257 are 257

Prime factors of 762 are 2 x 3 x 127

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

Given numbers are 687, 530, 257, 762

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

Apply this formula for all numbers.

Step1:

LCM(687, 530) = 364110

GCD(687, 530) = ( 687 x 530 ) / 364110

= 687 / 530

= 687

Step2:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

Step3:

LCM(1, 762) = 762

GCD(1, 762) = ( 1 x 762 ) / 762

= 1 / 762

= 1

So, Greatest Common Divisor of 687, 530, 257, 762 is 1
