Given numbers are 217, 595, 220, 680

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 595 are 5 x 7 x 17

Prime factors of 220 are 2 x 2 x 5 x 11

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

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

Given numbers are 217, 595, 220, 680

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

Apply this formula for all numbers.

Step1:

LCM(217, 595) = 18445

GCD(217, 595) = ( 217 x 595 ) / 18445

= 217 / 595

= 217

Step2:

LCM(7, 220) = 1540

GCD(7, 220) = ( 7 x 220 ) / 1540

= 7 / 220

= 7

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 217, 595, 220, 680 is 1
