Given numbers are 777, 749, 805, 831

The list of prime factors of all numbers are

Prime factors of 777 are 3 x 7 x 37

Prime factors of 749 are 7 x 107

Prime factors of 805 are 5 x 7 x 23

Prime factors of 831 are 3 x 277

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

Given numbers are 777, 749, 805, 831

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

Apply this formula for all numbers.

Step1:

LCM(777, 749) = 83139

GCD(777, 749) = ( 777 x 749 ) / 83139

= 777 / 749

= 777

Step2:

LCM(7, 805) = 805

GCD(7, 805) = ( 7 x 805 ) / 805

= 7 / 805

= 7

Step3:

LCM(7, 831) = 5817

GCD(7, 831) = ( 7 x 831 ) / 5817

= 7 / 831

= 7

So, Greatest Common Divisor of 777, 749, 805, 831 is 1
