Given numbers are 630, 956, 581, 123

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 956 are 2 x 2 x 239

Prime factors of 581 are 7 x 83

Prime factors of 123 are 3 x 41

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

Given numbers are 630, 956, 581, 123

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

Apply this formula for all numbers.

Step1:

LCM(630, 956) = 301140

GCD(630, 956) = ( 630 x 956 ) / 301140

= 630 / 956

= 630

Step2:

LCM(2, 581) = 1162

GCD(2, 581) = ( 2 x 581 ) / 1162

= 2 / 581

= 2

Step3:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1

So, Greatest Common Divisor of 630, 956, 581, 123 is 1
