Given numbers are 655, 764, 972, 851

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 764 are 2 x 2 x 191

Prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 851 are 23 x 37

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

Given numbers are 655, 764, 972, 851

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

Apply this formula for all numbers.

Step1:

LCM(655, 764) = 500420

GCD(655, 764) = ( 655 x 764 ) / 500420

= 655 / 764

= 655

Step2:

LCM(1, 972) = 972

GCD(1, 972) = ( 1 x 972 ) / 972

= 1 / 972

= 1

Step3:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

So, Greatest Common Divisor of 655, 764, 972, 851 is 1
