Given numbers are 868, 436, 324, 285

The list of prime factors of all numbers are

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

Prime factors of 436 are 2 x 2 x 109

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

Prime factors of 285 are 3 x 5 x 19

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

Given numbers are 868, 436, 324, 285

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

Apply this formula for all numbers.

Step1:

LCM(868, 436) = 94612

GCD(868, 436) = ( 868 x 436 ) / 94612

= 868 / 436

= 868

Step2:

LCM(4, 324) = 324

GCD(4, 324) = ( 4 x 324 ) / 324

= 4 / 324

= 4

Step3:

LCM(4, 285) = 1140

GCD(4, 285) = ( 4 x 285 ) / 1140

= 4 / 285

= 4

So, Greatest Common Divisor of 868, 436, 324, 285 is 1
