Given numbers are 104, 440, 20, 861

The list of prime factors of all numbers are

Prime factors of 104 are 2 x 2 x 2 x 13

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 20 are 2 x 2 x 5

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 104, 440, 20, 861

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

Apply this formula for all numbers.

Step1:

LCM(104, 440) = 5720

GCD(104, 440) = ( 104 x 440 ) / 5720

= 104 / 440

= 104

Step2:

LCM(8, 20) = 40

GCD(8, 20) = ( 8 x 20 ) / 40

= 8 / 20

= 8

Step3:

LCM(4, 861) = 3444

GCD(4, 861) = ( 4 x 861 ) / 3444

= 4 / 861

= 4

So, Greatest Common Divisor of 104, 440, 20, 861 is 1
