Given numbers are 126, 189, 580, 630

The list of prime factors of all numbers are

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 189 are 3 x 3 x 3 x 7

Prime factors of 580 are 2 x 2 x 5 x 29

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 126, 189, 580, 630

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

Apply this formula for all numbers.

Step1:

LCM(126, 189) = 378

GCD(126, 189) = ( 126 x 189 ) / 378

= 126 / 189

= 126

Step2:

LCM(63, 580) = 36540

GCD(63, 580) = ( 63 x 580 ) / 36540

= 63 / 580

= 63

Step3:

LCM(1, 630) = 630

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

= 1 / 630

= 1

So, Greatest Common Divisor of 126, 189, 580, 630 is 1
