Given numbers are 133, 780, 815, 939

The list of prime factors of all numbers are

Prime factors of 133 are 7 x 19

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 815 are 5 x 163

Prime factors of 939 are 3 x 313

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

Given numbers are 133, 780, 815, 939

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

Apply this formula for all numbers.

Step1:

LCM(133, 780) = 103740

GCD(133, 780) = ( 133 x 780 ) / 103740

= 133 / 780

= 133

Step2:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

Step3:

LCM(1, 939) = 939

GCD(1, 939) = ( 1 x 939 ) / 939

= 1 / 939

= 1

So, Greatest Common Divisor of 133, 780, 815, 939 is 1
