Given numbers are 610, 306, 865, 209

The list of prime factors of all numbers are

Prime factors of 610 are 2 x 5 x 61

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 865 are 5 x 173

Prime factors of 209 are 11 x 19

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

Given numbers are 610, 306, 865, 209

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

Apply this formula for all numbers.

Step1:

LCM(610, 306) = 93330

GCD(610, 306) = ( 610 x 306 ) / 93330

= 610 / 306

= 610

Step2:

LCM(2, 865) = 1730

GCD(2, 865) = ( 2 x 865 ) / 1730

= 2 / 865

= 2

Step3:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

So, Greatest Common Divisor of 610, 306, 865, 209 is 1
