Given numbers are 638, 832, 731, 228

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 832 are 2 x 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 731 are 17 x 43

Prime factors of 228 are 2 x 2 x 3 x 19

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

Given numbers are 638, 832, 731, 228

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

Apply this formula for all numbers.

Step1:

LCM(638, 832) = 265408

GCD(638, 832) = ( 638 x 832 ) / 265408

= 638 / 832

= 638

Step2:

LCM(2, 731) = 1462

GCD(2, 731) = ( 2 x 731 ) / 1462

= 2 / 731

= 2

Step3:

LCM(1, 228) = 228

GCD(1, 228) = ( 1 x 228 ) / 228

= 1 / 228

= 1

So, Greatest Common Divisor of 638, 832, 731, 228 is 1
