Given numbers are 756, 771, 631, 686

The list of prime factors of all numbers are

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 771 are 3 x 257

Prime factors of 631 are 631

Prime factors of 686 are 2 x 7 x 7 x 7

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

Given numbers are 756, 771, 631, 686

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

Apply this formula for all numbers.

Step1:

LCM(756, 771) = 194292

GCD(756, 771) = ( 756 x 771 ) / 194292

= 756 / 771

= 756

Step2:

LCM(3, 631) = 1893

GCD(3, 631) = ( 3 x 631 ) / 1893

= 3 / 631

= 3

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 756, 771, 631, 686 is 1
