Given numbers are 272, 124, 65, 680

The list of prime factors of all numbers are

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

Prime factors of 124 are 2 x 2 x 31

Prime factors of 65 are 5 x 13

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 272, 124, 65, 680

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

Apply this formula for all numbers.

Step1:

LCM(272, 124) = 8432

GCD(272, 124) = ( 272 x 124 ) / 8432

= 272 / 124

= 272

Step2:

LCM(4, 65) = 260

GCD(4, 65) = ( 4 x 65 ) / 260

= 4 / 65

= 4

Step3:

LCM(1, 680) = 680

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

= 1 / 680

= 1

So, Greatest Common Divisor of 272, 124, 65, 680 is 1
