Given numbers are 630, 490, 18, 557

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 490 are 2 x 5 x 7 x 7

Prime factors of 18 are 2 x 3 x 3

Prime factors of 557 are 557

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

Given numbers are 630, 490, 18, 557

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

Apply this formula for all numbers.

Step1:

LCM(630, 490) = 4410

GCD(630, 490) = ( 630 x 490 ) / 4410

= 630 / 490

= 630

Step2:

LCM(70, 18) = 630

GCD(70, 18) = ( 70 x 18 ) / 630

= 70 / 18

= 70

Step3:

LCM(2, 557) = 1114

GCD(2, 557) = ( 2 x 557 ) / 1114

= 2 / 557

= 2

So, Greatest Common Divisor of 630, 490, 18, 557 is 1
