Steps to Calculate GCD of 94, 42, 92, 81 using LCM Formula
Given numbers are 94, 42, 92, 81
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(94, 42) = 1974
GCD(94, 42) = ( 94 x 42 ) / 1974
= 94 / 42
= 94
Step2:
LCM(2, 92) = 92
GCD(2, 92) = ( 2 x 92 ) / 92
= 2 / 92
= 2
Step3:
LCM(2, 81) = 162
GCD(2, 81) = ( 2 x 81 ) / 162
= 2 / 81
= 2
So, Greatest Common Divisor of 94, 42, 92, 81 is 1
