Given numbers are 297, 387, 256, 780

The list of prime factors of all numbers are

Prime factors of 297 are 3 x 3 x 3 x 11

Prime factors of 387 are 3 x 3 x 43

Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

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

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

Given numbers are 297, 387, 256, 780

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

Apply this formula for all numbers.

Step1:

LCM(297, 387) = 12771

GCD(297, 387) = ( 297 x 387 ) / 12771

= 297 / 387

= 297

Step2:

LCM(9, 256) = 2304

GCD(9, 256) = ( 9 x 256 ) / 2304

= 9 / 256

= 9

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 297, 387, 256, 780 is 1
