Given numbers are 684, 945, 809, 615

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 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 809 are 809

Prime factors of 615 are 3 x 5 x 41

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

Given numbers are 684, 945, 809, 615

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

Apply this formula for all numbers.

Step1:

LCM(684, 945) = 71820

GCD(684, 945) = ( 684 x 945 ) / 71820

= 684 / 945

= 684

Step2:

LCM(9, 809) = 7281

GCD(9, 809) = ( 9 x 809 ) / 7281

= 9 / 809

= 9

Step3:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

So, Greatest Common Divisor of 684, 945, 809, 615 is 1
