Given numbers are 646, 700, 210, 329

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 700 are 2 x 2 x 5 x 5 x 7

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 329 are 7 x 47

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

Given numbers are 646, 700, 210, 329

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

Apply this formula for all numbers.

Step1:

LCM(646, 700) = 226100

GCD(646, 700) = ( 646 x 700 ) / 226100

= 646 / 700

= 646

Step2:

LCM(2, 210) = 210

GCD(2, 210) = ( 2 x 210 ) / 210

= 2 / 210

= 2

Step3:

LCM(2, 329) = 658

GCD(2, 329) = ( 2 x 329 ) / 658

= 2 / 329

= 2

So, Greatest Common Divisor of 646, 700, 210, 329 is 1
