Given numbers are 643, 264, 775, 630

The list of prime factors of all numbers are

Prime factors of 643 are 643

Prime factors of 264 are 2 x 2 x 2 x 3 x 11

Prime factors of 775 are 5 x 5 x 31

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 643, 264, 775, 630

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

Apply this formula for all numbers.

Step1:

LCM(643, 264) = 169752

GCD(643, 264) = ( 643 x 264 ) / 169752

= 643 / 264

= 643

Step2:

LCM(1, 775) = 775

GCD(1, 775) = ( 1 x 775 ) / 775

= 1 / 775

= 1

Step3:

LCM(1, 630) = 630

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

= 1 / 630

= 1

So, Greatest Common Divisor of 643, 264, 775, 630 is 1
