Given numbers are 771, 340, 649, 457

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 649 are 11 x 59

Prime factors of 457 are 457

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

Given numbers are 771, 340, 649, 457

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

Apply this formula for all numbers.

Step1:

LCM(771, 340) = 262140

GCD(771, 340) = ( 771 x 340 ) / 262140

= 771 / 340

= 771

Step2:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 771, 340, 649, 457 is 1
