Given numbers are 680, 363, 373, 644

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 363 are 3 x 11 x 11

Prime factors of 373 are 373

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

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

Given numbers are 680, 363, 373, 644

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

Apply this formula for all numbers.

Step1:

LCM(680, 363) = 246840

GCD(680, 363) = ( 680 x 363 ) / 246840

= 680 / 363

= 680

Step2:

LCM(1, 373) = 373

GCD(1, 373) = ( 1 x 373 ) / 373

= 1 / 373

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 680, 363, 373, 644 is 1
