The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 896 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 7

Prime factors of 147 are 3 x 7 x 7

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

Given numbers are 638, 558, 896, 147

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

Apply this formula for all numbers.

Step1:

LCM(638, 558) = 178002

GCD(638, 558) = ( 638 x 558 ) / 178002

= 638 / 558

= 638

Step2:

LCM(2, 896) = 896

GCD(2, 896) = ( 2 x 896 ) / 896

= 2 / 896

= 2

Step3:

LCM(2, 147) = 294

GCD(2, 147) = ( 2 x 147 ) / 294

= 2 / 147

= 2

So, Greatest Common Divisor of 638, 558, 896, 147 is 1
