Given numbers are 638, 740, 873, 394

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 740 are 2 x 2 x 5 x 37

Prime factors of 873 are 3 x 3 x 97

Prime factors of 394 are 2 x 197

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

Given numbers are 638, 740, 873, 394

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

Apply this formula for all numbers.

Step1:

LCM(638, 740) = 236060

GCD(638, 740) = ( 638 x 740 ) / 236060

= 638 / 740

= 638

Step2:

LCM(2, 873) = 1746

GCD(2, 873) = ( 2 x 873 ) / 1746

= 2 / 873

= 2

Step3:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

So, Greatest Common Divisor of 638, 740, 873, 394 is 1
