Given numbers are 786, 656, 687, 777

The list of prime factors of all numbers are

Prime factors of 786 are 2 x 3 x 131

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 687 are 3 x 229

Prime factors of 777 are 3 x 7 x 37

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

Given numbers are 786, 656, 687, 777

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

Apply this formula for all numbers.

Step1:

LCM(786, 656) = 257808

GCD(786, 656) = ( 786 x 656 ) / 257808

= 786 / 656

= 786

Step2:

LCM(2, 687) = 1374

GCD(2, 687) = ( 2 x 687 ) / 1374

= 2 / 687

= 2

Step3:

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

= 1 / 777

= 1

So, Greatest Common Divisor of 786, 656, 687, 777 is 1
