Given numbers are 680, 878, 368, 485

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 878 are 2 x 439

Prime factors of 368 are 2 x 2 x 2 x 2 x 23

Prime factors of 485 are 5 x 97

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

Given numbers are 680, 878, 368, 485

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

Apply this formula for all numbers.

Step1:

LCM(680, 878) = 298520

GCD(680, 878) = ( 680 x 878 ) / 298520

= 680 / 878

= 680

Step2:

LCM(2, 368) = 368

GCD(2, 368) = ( 2 x 368 ) / 368

= 2 / 368

= 2

Step3:

LCM(2, 485) = 970

GCD(2, 485) = ( 2 x 485 ) / 970

= 2 / 485

= 2

So, Greatest Common Divisor of 680, 878, 368, 485 is 1
