Given numbers are 133, 308, 637, 618

The list of prime factors of all numbers are

Prime factors of 133 are 7 x 19

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 637 are 7 x 7 x 13

Prime factors of 618 are 2 x 3 x 103

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

Given numbers are 133, 308, 637, 618

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

Apply this formula for all numbers.

Step1:

LCM(133, 308) = 5852

GCD(133, 308) = ( 133 x 308 ) / 5852

= 133 / 308

= 133

Step2:

LCM(7, 637) = 637

GCD(7, 637) = ( 7 x 637 ) / 637

= 7 / 637

= 7

Step3:

LCM(7, 618) = 4326

GCD(7, 618) = ( 7 x 618 ) / 4326

= 7 / 618

= 7

So, Greatest Common Divisor of 133, 308, 637, 618 is 1
