Given numbers are 780, 459, 660, 193

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 459 are 3 x 3 x 3 x 17

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 193 are 193

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

Given numbers are 780, 459, 660, 193

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

Apply this formula for all numbers.

Step1:

LCM(780, 459) = 119340

GCD(780, 459) = ( 780 x 459 ) / 119340

= 780 / 459

= 780

Step2:

LCM(3, 660) = 660

GCD(3, 660) = ( 3 x 660 ) / 660

= 3 / 660

= 3

Step3:

LCM(3, 193) = 579

GCD(3, 193) = ( 3 x 193 ) / 579

= 3 / 193

= 3

So, Greatest Common Divisor of 780, 459, 660, 193 is 1
