Given numbers are 397, 829, 520, 630

The list of prime factors of all numbers are

Prime factors of 397 are 397

Prime factors of 829 are 829

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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 397, 829, 520, 630

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

Apply this formula for all numbers.

Step1:

LCM(397, 829) = 329113

GCD(397, 829) = ( 397 x 829 ) / 329113

= 397 / 829

= 397

Step2:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

Step3:

LCM(1, 630) = 630

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

= 1 / 630

= 1

So, Greatest Common Divisor of 397, 829, 520, 630 is 1
