Given numbers are 630, 615, 122, 449

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 615 are 3 x 5 x 41

Prime factors of 122 are 2 x 61

Prime factors of 449 are 449

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

Given numbers are 630, 615, 122, 449

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

Apply this formula for all numbers.

Step1:

LCM(630, 615) = 25830

GCD(630, 615) = ( 630 x 615 ) / 25830

= 630 / 615

= 630

Step2:

LCM(15, 122) = 1830

GCD(15, 122) = ( 15 x 122 ) / 1830

= 15 / 122

= 15

Step3:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1

So, Greatest Common Divisor of 630, 615, 122, 449 is 1
