Given numbers are 684, 665, 644, 183

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 665 are 5 x 7 x 19

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 183 are 3 x 61

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

Given numbers are 684, 665, 644, 183

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

Apply this formula for all numbers.

Step1:

LCM(684, 665) = 23940

GCD(684, 665) = ( 684 x 665 ) / 23940

= 684 / 665

= 684

Step2:

LCM(19, 644) = 12236

GCD(19, 644) = ( 19 x 644 ) / 12236

= 19 / 644

= 19

Step3:

LCM(1, 183) = 183

GCD(1, 183) = ( 1 x 183 ) / 183

= 1 / 183

= 1

So, Greatest Common Divisor of 684, 665, 644, 183 is 1
