Given numbers are 423, 838, 951, 630

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 838 are 2 x 419

Prime factors of 951 are 3 x 317

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 423, 838, 951, 630

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

Apply this formula for all numbers.

Step1:

LCM(423, 838) = 354474

GCD(423, 838) = ( 423 x 838 ) / 354474

= 423 / 838

= 423

Step2:

LCM(1, 951) = 951

GCD(1, 951) = ( 1 x 951 ) / 951

= 1 / 951

= 1

Step3:

LCM(1, 630) = 630

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

= 1 / 630

= 1

So, Greatest Common Divisor of 423, 838, 951, 630 is 1
