Given numbers are 258, 228, 694, 649

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 694 are 2 x 347

Prime factors of 649 are 11 x 59

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

Given numbers are 258, 228, 694, 649

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

Apply this formula for all numbers.

Step1:

LCM(258, 228) = 9804

GCD(258, 228) = ( 258 x 228 ) / 9804

= 258 / 228

= 258

Step2:

LCM(6, 694) = 2082

GCD(6, 694) = ( 6 x 694 ) / 2082

= 6 / 694

= 6

Step3:

LCM(2, 649) = 1298

GCD(2, 649) = ( 2 x 649 ) / 1298

= 2 / 649

= 2

So, Greatest Common Divisor of 258, 228, 694, 649 is 1
