Given numbers are 617, 780, 221, 512

The list of prime factors of all numbers are

Prime factors of 617 are 617

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 221 are 13 x 17

Prime factors of 512 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Given numbers are 617, 780, 221, 512

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

Apply this formula for all numbers.

Step1:

LCM(617, 780) = 481260

GCD(617, 780) = ( 617 x 780 ) / 481260

= 617 / 780

= 617

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 512) = 512

GCD(1, 512) = ( 1 x 512 ) / 512

= 1 / 512

= 1

So, Greatest Common Divisor of 617, 780, 221, 512 is 1
