Steps to Calculate GCD of 53, 45, 23, 18 using LCM Formula
Given numbers are 53, 45, 23, 18
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(53, 45) = 2385
GCD(53, 45) = ( 53 x 45 ) / 2385
= 53 / 45
= 53
Step2:
LCM(1, 23) = 23
GCD(1, 23) = ( 1 x 23 ) / 23
= 1 / 23
= 1
Step3:
LCM(1, 18) = 18
GCD(1, 18) = ( 1 x 18 ) / 18
= 1 / 18
= 1
So, Greatest Common Divisor of 53, 45, 23, 18 is 1
