Given numbers are 769, 666, 660, 687

The list of prime factors of all numbers are

Prime factors of 769 are 769

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 687 are 3 x 229

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

Given numbers are 769, 666, 660, 687

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

Apply this formula for all numbers.

Step1:

LCM(769, 666) = 512154

GCD(769, 666) = ( 769 x 666 ) / 512154

= 769 / 666

= 769

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 769, 666, 660, 687 is 1
