Given numbers are 771, 756, 510, 815

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

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

Prime factors of 510 are 2 x 3 x 5 x 17

Prime factors of 815 are 5 x 163

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

Given numbers are 771, 756, 510, 815

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

Apply this formula for all numbers.

Step1:

LCM(771, 756) = 194292

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

= 771 / 756

= 771

Step2:

LCM(3, 510) = 510

GCD(3, 510) = ( 3 x 510 ) / 510

= 3 / 510

= 3

Step3:

LCM(3, 815) = 2445

GCD(3, 815) = ( 3 x 815 ) / 2445

= 3 / 815

= 3

So, Greatest Common Divisor of 771, 756, 510, 815 is 1
