Given numbers are 638, 690, 258, 367

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

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

Prime factors of 258 are 2 x 3 x 43

Prime factors of 367 are 367

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

Given numbers are 638, 690, 258, 367

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

Apply this formula for all numbers.

Step1:

LCM(638, 690) = 220110

GCD(638, 690) = ( 638 x 690 ) / 220110

= 638 / 690

= 638

Step2:

LCM(2, 258) = 258

GCD(2, 258) = ( 2 x 258 ) / 258

= 2 / 258

= 2

Step3:

LCM(2, 367) = 734

GCD(2, 367) = ( 2 x 367 ) / 734

= 2 / 367

= 2

So, Greatest Common Divisor of 638, 690, 258, 367 is 1
