Given numbers are 861, 480, 580, 189

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 189 are 3 x 3 x 3 x 7

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

Given numbers are 861, 480, 580, 189

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

Apply this formula for all numbers.

Step1:

LCM(861, 480) = 137760

GCD(861, 480) = ( 861 x 480 ) / 137760

= 861 / 480

= 861

Step2:

LCM(3, 580) = 1740

GCD(3, 580) = ( 3 x 580 ) / 1740

= 3 / 580

= 3

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 861, 480, 580, 189 is 1
