Given numbers are 630, 159, 445, 124

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 159 are 3 x 53

Prime factors of 445 are 5 x 89

Prime factors of 124 are 2 x 2 x 31

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

Given numbers are 630, 159, 445, 124

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

Apply this formula for all numbers.

Step1:

LCM(630, 159) = 33390

GCD(630, 159) = ( 630 x 159 ) / 33390

= 630 / 159

= 630

Step2:

LCM(3, 445) = 1335

GCD(3, 445) = ( 3 x 445 ) / 1335

= 3 / 445

= 3

Step3:

LCM(1, 124) = 124

GCD(1, 124) = ( 1 x 124 ) / 124

= 1 / 124

= 1

So, Greatest Common Divisor of 630, 159, 445, 124 is 1
