Given numbers are 915, 279, 84, 868

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

Apply this formula for all numbers.

Step1:

LCM(915, 279) = 85095

GCD(915, 279) = ( 915 x 279 ) / 85095

= 915 / 279

= 915

Step2:

LCM(3, 84) = 84

GCD(3, 84) = ( 3 x 84 ) / 84

= 3 / 84

= 3

Step3:

LCM(3, 868) = 2604

GCD(3, 868) = ( 3 x 868 ) / 2604

= 3 / 868

= 3

So, Greatest Common Divisor of 915, 279, 84, 868 is 1
