Given numbers are 780, 386, 553, 294

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 386 are 2 x 193

Prime factors of 553 are 7 x 79

Prime factors of 294 are 2 x 3 x 7 x 7

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

Given numbers are 780, 386, 553, 294

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

Apply this formula for all numbers.

Step1:

LCM(780, 386) = 150540

GCD(780, 386) = ( 780 x 386 ) / 150540

= 780 / 386

= 780

Step2:

LCM(2, 553) = 1106

GCD(2, 553) = ( 2 x 553 ) / 1106

= 2 / 553

= 2

Step3:

LCM(1, 294) = 294

GCD(1, 294) = ( 1 x 294 ) / 294

= 1 / 294

= 1

So, Greatest Common Divisor of 780, 386, 553, 294 is 1
