Given numbers are 638, 708, 742, 897

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 708 are 2 x 2 x 3 x 59

Prime factors of 742 are 2 x 7 x 53

Prime factors of 897 are 3 x 13 x 23

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

Given numbers are 638, 708, 742, 897

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

Apply this formula for all numbers.

Step1:

LCM(638, 708) = 225852

GCD(638, 708) = ( 638 x 708 ) / 225852

= 638 / 708

= 638

Step2:

LCM(2, 742) = 742

GCD(2, 742) = ( 2 x 742 ) / 742

= 2 / 742

= 2

Step3:

LCM(2, 897) = 1794

GCD(2, 897) = ( 2 x 897 ) / 1794

= 2 / 897

= 2

So, Greatest Common Divisor of 638, 708, 742, 897 is 1
