Given numbers are 187, 375, 21, 630

The list of prime factors of all numbers are

Prime factors of 187 are 11 x 17

Prime factors of 375 are 3 x 5 x 5 x 5

Prime factors of 21 are 3 x 7

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 187, 375, 21, 630

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

Apply this formula for all numbers.

Step1:

LCM(187, 375) = 70125

GCD(187, 375) = ( 187 x 375 ) / 70125

= 187 / 375

= 187

Step2:

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

= 1 / 21

= 1

Step3:

LCM(1, 630) = 630

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

= 1 / 630

= 1

So, Greatest Common Divisor of 187, 375, 21, 630 is 1
