The list of prime factors of all numbers are

Prime factors of 626 are 2 x 313

Prime factors of 903 are 3 x 7 x 43

Prime factors of 678 are 2 x 3 x 113

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 626, 903, 678, 840

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

Apply this formula for all numbers.

Step1:

LCM(626, 903) = 565278

GCD(626, 903) = ( 626 x 903 ) / 565278

= 626 / 903

= 626

Step2:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 626, 903, 678, 840 is 1
