Given numbers are 684, 780, 560, 439

The list of prime factors of all numbers are

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

Prime factors of 439 are 439

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

Given numbers are 684, 780, 560, 439

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

Apply this formula for all numbers.

Step1:

LCM(684, 780) = 44460

GCD(684, 780) = ( 684 x 780 ) / 44460

= 684 / 780

= 684

Step2:

LCM(12, 560) = 1680

GCD(12, 560) = ( 12 x 560 ) / 1680

= 12 / 560

= 12

Step3:

LCM(4, 439) = 1756

GCD(4, 439) = ( 4 x 439 ) / 1756

= 4 / 439

= 4

So, Greatest Common Divisor of 684, 780, 560, 439 is 1
