Given numbers are 641, 126, 375, 630

The list of prime factors of all numbers are

Prime factors of 641 are 641

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

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

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 641, 126, 375, 630

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

Apply this formula for all numbers.

Step1:

LCM(641, 126) = 80766

GCD(641, 126) = ( 641 x 126 ) / 80766

= 641 / 126

= 641

Step2:

LCM(1, 375) = 375

GCD(1, 375) = ( 1 x 375 ) / 375

= 1 / 375

= 1

Step3:

LCM(1, 630) = 630

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

= 1 / 630

= 1

So, Greatest Common Divisor of 641, 126, 375, 630 is 1
