Given numbers are 205, 564, 840, 249

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

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

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 249 are 3 x 83

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

Given numbers are 205, 564, 840, 249

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

Apply this formula for all numbers.

Step1:

LCM(205, 564) = 115620

GCD(205, 564) = ( 205 x 564 ) / 115620

= 205 / 564

= 205

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

So, Greatest Common Divisor of 205, 564, 840, 249 is 1
