Given numbers are 630, 408, 325, 490

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 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 325 are 5 x 5 x 13

Prime factors of 490 are 2 x 5 x 7 x 7

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

Given numbers are 630, 408, 325, 490

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

Apply this formula for all numbers.

Step1:

LCM(630, 408) = 42840

GCD(630, 408) = ( 630 x 408 ) / 42840

= 630 / 408

= 630

Step2:

LCM(6, 325) = 1950

GCD(6, 325) = ( 6 x 325 ) / 1950

= 6 / 325

= 6

Step3:

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

= 1 / 490

= 1

So, Greatest Common Divisor of 630, 408, 325, 490 is 1
