Given numbers are 764, 215, 405, 688

The list of prime factors of all numbers are

Prime factors of 764 are 2 x 2 x 191

Prime factors of 215 are 5 x 43

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

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

Given numbers are 764, 215, 405, 688

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

Apply this formula for all numbers.

Step1:

LCM(764, 215) = 164260

GCD(764, 215) = ( 764 x 215 ) / 164260

= 764 / 215

= 764

Step2:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 764, 215, 405, 688 is 1
