Given numbers are 771, 256, 744, 819

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

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

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 819 are 3 x 3 x 7 x 13

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

Given numbers are 771, 256, 744, 819

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

Apply this formula for all numbers.

Step1:

LCM(771, 256) = 197376

GCD(771, 256) = ( 771 x 256 ) / 197376

= 771 / 256

= 771

Step2:

LCM(1, 744) = 744

GCD(1, 744) = ( 1 x 744 ) / 744

= 1 / 744

= 1

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 771, 256, 744, 819 is 1
