Given numbers are 684, 219, 805, 975

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 219 are 3 x 73

Prime factors of 805 are 5 x 7 x 23

Prime factors of 975 are 3 x 5 x 5 x 13

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

Given numbers are 684, 219, 805, 975

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

Apply this formula for all numbers.

Step1:

LCM(684, 219) = 49932

GCD(684, 219) = ( 684 x 219 ) / 49932

= 684 / 219

= 684

Step2:

LCM(3, 805) = 2415

GCD(3, 805) = ( 3 x 805 ) / 2415

= 3 / 805

= 3

Step3:

LCM(1, 975) = 975

GCD(1, 975) = ( 1 x 975 ) / 975

= 1 / 975

= 1

So, Greatest Common Divisor of 684, 219, 805, 975 is 1
