Given numbers are 854, 840, 915
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(854, 840) = 51240
GCD(854, 840) = ( 854 x 840 ) / 51240
= 854 / 840
= 854
Step2:
LCM(14, 915) = 12810
GCD(14, 915) = ( 14 x 915 ) / 12810
= 14 / 915
= 14
So, Greatest Common Divisor of 854, 840, 915 is 1
