Steps to Calculate GCD of 71, 66, 99, 45 using LCM Formula
Given numbers are 71, 66, 99, 45
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(71, 66) = 4686
GCD(71, 66) = ( 71 x 66 ) / 4686
= 71 / 66
= 71
Step2:
LCM(1, 99) = 99
GCD(1, 99) = ( 1 x 99 ) / 99
= 1 / 99
= 1
Step3:
LCM(1, 45) = 45
GCD(1, 45) = ( 1 x 45 ) / 45
= 1 / 45
= 1
So, Greatest Common Divisor of 71, 66, 99, 45 is 1
