Given numbers are 780, 742, 321, 133

The list of prime factors of all numbers are

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

Prime factors of 742 are 2 x 7 x 53

Prime factors of 321 are 3 x 107

Prime factors of 133 are 7 x 19

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

Given numbers are 780, 742, 321, 133

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

Apply this formula for all numbers.

Step1:

LCM(780, 742) = 289380

GCD(780, 742) = ( 780 x 742 ) / 289380

= 780 / 742

= 780

Step2:

LCM(2, 321) = 642

GCD(2, 321) = ( 2 x 321 ) / 642

= 2 / 321

= 2

Step3:

LCM(1, 133) = 133

GCD(1, 133) = ( 1 x 133 ) / 133

= 1 / 133

= 1

So, Greatest Common Divisor of 780, 742, 321, 133 is 1
