Given numbers are 417, 190, 639, 690

The list of prime factors of all numbers are

Prime factors of 417 are 3 x 139

Prime factors of 190 are 2 x 5 x 19

Prime factors of 639 are 3 x 3 x 71

Prime factors of 690 are 2 x 3 x 5 x 23

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

Given numbers are 417, 190, 639, 690

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

Apply this formula for all numbers.

Step1:

LCM(417, 190) = 79230

GCD(417, 190) = ( 417 x 190 ) / 79230

= 417 / 190

= 417

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 417, 190, 639, 690 is 1
