Given numbers are 861, 585, 470, 900

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 585 are 3 x 3 x 5 x 13

Prime factors of 470 are 2 x 5 x 47

Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5

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

Given numbers are 861, 585, 470, 900

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

Apply this formula for all numbers.

Step1:

LCM(861, 585) = 167895

GCD(861, 585) = ( 861 x 585 ) / 167895

= 861 / 585

= 861

Step2:

LCM(3, 470) = 1410

GCD(3, 470) = ( 3 x 470 ) / 1410

= 3 / 470

= 3

Step3:

LCM(1, 900) = 900

GCD(1, 900) = ( 1 x 900 ) / 900

= 1 / 900

= 1

So, Greatest Common Divisor of 861, 585, 470, 900 is 1
