Given numbers are 680, 648, 681, 660

The list of prime factors of all numbers are

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

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 681 are 3 x 227

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 680, 648, 681, 660

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

Apply this formula for all numbers.

Step1:

LCM(680, 648) = 55080

GCD(680, 648) = ( 680 x 648 ) / 55080

= 680 / 648

= 680

Step2:

LCM(8, 681) = 5448

GCD(8, 681) = ( 8 x 681 ) / 5448

= 8 / 681

= 8

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 680, 648, 681, 660 is 1
