Given numbers are 685, 246, 648, 204

The list of prime factors of all numbers are

Prime factors of 685 are 5 x 137

Prime factors of 246 are 2 x 3 x 41

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 204 are 2 x 2 x 3 x 17

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

Given numbers are 685, 246, 648, 204

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

Apply this formula for all numbers.

Step1:

LCM(685, 246) = 168510

GCD(685, 246) = ( 685 x 246 ) / 168510

= 685 / 246

= 685

Step2:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

Step3:

LCM(1, 204) = 204

GCD(1, 204) = ( 1 x 204 ) / 204

= 1 / 204

= 1

So, Greatest Common Divisor of 685, 246, 648, 204 is 1
