Given numbers are 771, 910, 645, 838

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

Prime factors of 910 are 2 x 5 x 7 x 13

Prime factors of 645 are 3 x 5 x 43

Prime factors of 838 are 2 x 419

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

Given numbers are 771, 910, 645, 838

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

Apply this formula for all numbers.

Step1:

LCM(771, 910) = 701610

GCD(771, 910) = ( 771 x 910 ) / 701610

= 771 / 910

= 771

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

Step3:

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

= 1 / 838

= 1

So, Greatest Common Divisor of 771, 910, 645, 838 is 1
