Given numbers are 861, 564, 290, 205

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 564 are 2 x 2 x 3 x 47

Prime factors of 290 are 2 x 5 x 29

Prime factors of 205 are 5 x 41

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

Given numbers are 861, 564, 290, 205

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

Apply this formula for all numbers.

Step1:

LCM(861, 564) = 161868

GCD(861, 564) = ( 861 x 564 ) / 161868

= 861 / 564

= 861

Step2:

LCM(3, 290) = 870

GCD(3, 290) = ( 3 x 290 ) / 870

= 3 / 290

= 3

Step3:

LCM(1, 205) = 205

GCD(1, 205) = ( 1 x 205 ) / 205

= 1 / 205

= 1

So, Greatest Common Divisor of 861, 564, 290, 205 is 1
