Given numbers are 868, 805, 209, 912

The list of prime factors of all numbers are

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

Prime factors of 805 are 5 x 7 x 23

Prime factors of 209 are 11 x 19

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

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

Given numbers are 868, 805, 209, 912

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

Apply this formula for all numbers.

Step1:

LCM(868, 805) = 99820

GCD(868, 805) = ( 868 x 805 ) / 99820

= 868 / 805

= 868

Step2:

LCM(7, 209) = 1463

GCD(7, 209) = ( 7 x 209 ) / 1463

= 7 / 209

= 7

Step3:

LCM(1, 912) = 912

GCD(1, 912) = ( 1 x 912 ) / 912

= 1 / 912

= 1

So, Greatest Common Divisor of 868, 805, 209, 912 is 1
