Given numbers are 574, 166, 785, 638

The list of prime factors of all numbers are

Prime factors of 574 are 2 x 7 x 41

Prime factors of 166 are 2 x 83

Prime factors of 785 are 5 x 157

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 574, 166, 785, 638

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

Apply this formula for all numbers.

Step1:

LCM(574, 166) = 47642

GCD(574, 166) = ( 574 x 166 ) / 47642

= 574 / 166

= 574

Step2:

LCM(2, 785) = 1570

GCD(2, 785) = ( 2 x 785 ) / 1570

= 2 / 785

= 2

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 574, 166, 785, 638 is 1
