Given numbers are 624, 630, 489, 676

The list of prime factors of all numbers are

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

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

Prime factors of 489 are 3 x 163

Prime factors of 676 are 2 x 2 x 13 x 13

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

Given numbers are 624, 630, 489, 676

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

Apply this formula for all numbers.

Step1:

LCM(624, 630) = 65520

GCD(624, 630) = ( 624 x 630 ) / 65520

= 624 / 630

= 624

Step2:

LCM(6, 489) = 978

GCD(6, 489) = ( 6 x 489 ) / 978

= 6 / 489

= 6

Step3:

LCM(3, 676) = 2028

GCD(3, 676) = ( 3 x 676 ) / 2028

= 3 / 676

= 3

So, Greatest Common Divisor of 624, 630, 489, 676 is 1
