Given numbers are 868, 903, 309, 209

The list of prime factors of all numbers are

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 903 are 3 x 7 x 43

Prime factors of 309 are 3 x 103

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 868, 903, 309, 209

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

Apply this formula for all numbers.

Step1:

LCM(868, 903) = 111972

GCD(868, 903) = ( 868 x 903 ) / 111972

= 868 / 903

= 868

Step2:

LCM(7, 309) = 2163

GCD(7, 309) = ( 7 x 309 ) / 2163

= 7 / 309

= 7

Step3:

LCM(1, 209) = 209

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

= 1 / 209

= 1

So, Greatest Common Divisor of 868, 903, 309, 209 is 1
