Given numbers are 873, 861, 660, 782

The list of prime factors of all numbers are

Prime factors of 873 are 3 x 3 x 97

Prime factors of 861 are 3 x 7 x 41

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 782 are 2 x 17 x 23

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

Given numbers are 873, 861, 660, 782

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

Apply this formula for all numbers.

Step1:

LCM(873, 861) = 250551

GCD(873, 861) = ( 873 x 861 ) / 250551

= 873 / 861

= 873

Step2:

LCM(3, 660) = 660

GCD(3, 660) = ( 3 x 660 ) / 660

= 3 / 660

= 3

Step3:

LCM(3, 782) = 2346

GCD(3, 782) = ( 3 x 782 ) / 2346

= 3 / 782

= 3

So, Greatest Common Divisor of 873, 861, 660, 782 is 1
