Given numbers are 306, 657, 638, 658

The list of prime factors of all numbers are

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 657 are 3 x 3 x 73

Prime factors of 638 are 2 x 11 x 29

Prime factors of 658 are 2 x 7 x 47

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

Given numbers are 306, 657, 638, 658

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

Apply this formula for all numbers.

Step1:

LCM(306, 657) = 22338

GCD(306, 657) = ( 306 x 657 ) / 22338

= 306 / 657

= 306

Step2:

LCM(9, 638) = 5742

GCD(9, 638) = ( 9 x 638 ) / 5742

= 9 / 638

= 9

Step3:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 306, 657, 638, 658 is 1
