Given numbers are 645, 911, 231, 764

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 911 are 911

Prime factors of 231 are 3 x 7 x 11

Prime factors of 764 are 2 x 2 x 191

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

Given numbers are 645, 911, 231, 764

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

Apply this formula for all numbers.

Step1:

LCM(645, 911) = 587595

GCD(645, 911) = ( 645 x 911 ) / 587595

= 645 / 911

= 645

Step2:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

Step3:

LCM(1, 764) = 764

GCD(1, 764) = ( 1 x 764 ) / 764

= 1 / 764

= 1

So, Greatest Common Divisor of 645, 911, 231, 764 is 1
