Given numbers are 680, 116, 474, 261

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 116 are 2 x 2 x 29

Prime factors of 474 are 2 x 3 x 79

Prime factors of 261 are 3 x 3 x 29

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

Given numbers are 680, 116, 474, 261

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

Apply this formula for all numbers.

Step1:

LCM(680, 116) = 19720

GCD(680, 116) = ( 680 x 116 ) / 19720

= 680 / 116

= 680

Step2:

LCM(4, 474) = 948

GCD(4, 474) = ( 4 x 474 ) / 948

= 4 / 474

= 4

Step3:

LCM(2, 261) = 522

GCD(2, 261) = ( 2 x 261 ) / 522

= 2 / 261

= 2

So, Greatest Common Divisor of 680, 116, 474, 261 is 1
