Given numbers are 638, 766, 940, 403

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 766 are 2 x 383

Prime factors of 940 are 2 x 2 x 5 x 47

Prime factors of 403 are 13 x 31

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

Given numbers are 638, 766, 940, 403

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

Apply this formula for all numbers.

Step1:

LCM(638, 766) = 244354

GCD(638, 766) = ( 638 x 766 ) / 244354

= 638 / 766

= 638

Step2:

LCM(2, 940) = 940

GCD(2, 940) = ( 2 x 940 ) / 940

= 2 / 940

= 2

Step3:

LCM(2, 403) = 806

GCD(2, 403) = ( 2 x 403 ) / 806

= 2 / 403

= 2

So, Greatest Common Divisor of 638, 766, 940, 403 is 1
