Given numbers are 861, 988, 773, 810

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 988 are 2 x 2 x 13 x 19

Prime factors of 773 are 773

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

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

Given numbers are 861, 988, 773, 810

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

Apply this formula for all numbers.

Step1:

LCM(861, 988) = 850668

GCD(861, 988) = ( 861 x 988 ) / 850668

= 861 / 988

= 861

Step2:

LCM(1, 773) = 773

GCD(1, 773) = ( 1 x 773 ) / 773

= 1 / 773

= 1

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 861, 988, 773, 810 is 1
