Given numbers are 387, 570, 520, 630

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 570 are 2 x 3 x 5 x 19

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 387, 570, 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(387, 570) = 73530

GCD(387, 570) = ( 387 x 570 ) / 73530

= 387 / 570

= 387

Step2:

LCM(3, 520) = 1560

GCD(3, 520) = ( 3 x 520 ) / 1560

= 3 / 520

= 3

Step3:

LCM(1, 630) = 630

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

= 1 / 630

= 1

So, Greatest Common Divisor of 387, 570, 520, 630 is 1
