Given numbers are 861, 417, 857, 180

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 417 are 3 x 139

Prime factors of 857 are 857

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

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

Given numbers are 861, 417, 857, 180

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

Apply this formula for all numbers.

Step1:

LCM(861, 417) = 119679

GCD(861, 417) = ( 861 x 417 ) / 119679

= 861 / 417

= 861

Step2:

LCM(3, 857) = 2571

GCD(3, 857) = ( 3 x 857 ) / 2571

= 3 / 857

= 3

Step3:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

So, Greatest Common Divisor of 861, 417, 857, 180 is 1
