Given numbers are 626, 646, 629, 810

The list of prime factors of all numbers are

Prime factors of 626 are 2 x 313

Prime factors of 646 are 2 x 17 x 19

Prime factors of 629 are 17 x 37

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

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

Given numbers are 626, 646, 629, 810

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

Apply this formula for all numbers.

Step1:

LCM(626, 646) = 202198

GCD(626, 646) = ( 626 x 646 ) / 202198

= 626 / 646

= 626

Step2:

LCM(2, 629) = 1258

GCD(2, 629) = ( 2 x 629 ) / 1258

= 2 / 629

= 2

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 626, 646, 629, 810 is 1
