Given numbers are 630, 138, 329, 320

The list of prime factors of all numbers are

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 138 are 2 x 3 x 23

Prime factors of 329 are 7 x 47

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 630, 138, 329, 320

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

Apply this formula for all numbers.

Step1:

LCM(630, 138) = 14490

GCD(630, 138) = ( 630 x 138 ) / 14490

= 630 / 138

= 630

Step2:

LCM(6, 329) = 1974

GCD(6, 329) = ( 6 x 329 ) / 1974

= 6 / 329

= 6

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 630, 138, 329, 320 is 1
