Given numbers are 920, 851, 873, 861

The list of prime factors of all numbers are

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 851 are 23 x 37

Prime factors of 873 are 3 x 3 x 97

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 920, 851, 873, 861

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

Apply this formula for all numbers.

Step1:

LCM(920, 851) = 34040

GCD(920, 851) = ( 920 x 851 ) / 34040

= 920 / 851

= 920

Step2:

LCM(23, 873) = 20079

GCD(23, 873) = ( 23 x 873 ) / 20079

= 23 / 873

= 23

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 920, 851, 873, 861 is 1
