Given numbers are 771, 756, 664, 761

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 664 are 2 x 2 x 2 x 83

Prime factors of 761 are 761

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

Given numbers are 771, 756, 664, 761

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, 664) = 1992

GCD(3, 664) = ( 3 x 664 ) / 1992

= 3 / 664

= 3

Step3:

LCM(1, 761) = 761

GCD(1, 761) = ( 1 x 761 ) / 761

= 1 / 761

= 1

So, Greatest Common Divisor of 771, 756, 664, 761 is 1
