Given numbers are 861, 903, 648, 626

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 903 are 3 x 7 x 43

Prime factors of 648 are 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 626 are 2 x 313

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

Given numbers are 861, 903, 648, 626

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

Apply this formula for all numbers.

Step1:

LCM(861, 903) = 37023

GCD(861, 903) = ( 861 x 903 ) / 37023

= 861 / 903

= 861

Step2:

LCM(21, 648) = 4536

GCD(21, 648) = ( 21 x 648 ) / 4536

= 21 / 648

= 21

Step3:

LCM(3, 626) = 1878

GCD(3, 626) = ( 3 x 626 ) / 1878

= 3 / 626

= 3

So, Greatest Common Divisor of 861, 903, 648, 626 is 1
