Steps to Calculate GCD of 27, 68, 84, 17 using LCM Formula
Given numbers are 27, 68, 84, 17
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(27, 68) = 1836
GCD(27, 68) = ( 27 x 68 ) / 1836
= 27 / 68
= 27
Step2:
LCM(1, 84) = 84
GCD(1, 84) = ( 1 x 84 ) / 84
= 1 / 84
= 1
Step3:
LCM(1, 17) = 17
GCD(1, 17) = ( 1 x 17 ) / 17
= 1 / 17
= 1
So, Greatest Common Divisor of 27, 68, 84, 17 is 1
