Given numbers are 188, 431, 249, 630

The list of prime factors of all numbers are

Prime factors of 188 are 2 x 2 x 47

Prime factors of 431 are 431

Prime factors of 249 are 3 x 83

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 188, 431, 249, 630

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

Apply this formula for all numbers.

Step1:

LCM(188, 431) = 81028

GCD(188, 431) = ( 188 x 431 ) / 81028

= 188 / 431

= 188

Step2:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

Step3:

LCM(1, 630) = 630

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

= 1 / 630

= 1

So, Greatest Common Divisor of 188, 431, 249, 630 is 1
