Given numbers are 609, 345, 218, 630

The list of prime factors of all numbers are

Prime factors of 609 are 3 x 7 x 29

Prime factors of 345 are 3 x 5 x 23

Prime factors of 218 are 2 x 109

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

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

Given numbers are 609, 345, 218, 630

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

Apply this formula for all numbers.

Step1:

LCM(609, 345) = 70035

GCD(609, 345) = ( 609 x 345 ) / 70035

= 609 / 345

= 609

Step2:

LCM(3, 218) = 654

GCD(3, 218) = ( 3 x 218 ) / 654

= 3 / 218

= 3

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 609, 345, 218, 630 is 1
