Given numbers are 255, 645, 680, 481

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 645 are 3 x 5 x 43

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 481 are 13 x 37

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

Given numbers are 255, 645, 680, 481

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

Apply this formula for all numbers.

Step1:

LCM(255, 645) = 10965

GCD(255, 645) = ( 255 x 645 ) / 10965

= 255 / 645

= 255

Step2:

LCM(15, 680) = 2040

GCD(15, 680) = ( 15 x 680 ) / 2040

= 15 / 680

= 15

Step3:

LCM(5, 481) = 2405

GCD(5, 481) = ( 5 x 481 ) / 2405

= 5 / 481

= 5

So, Greatest Common Divisor of 255, 645, 680, 481 is 1
