Steps to Calculate GCD of 72, 36, 18, 47 using LCM Formula
Given numbers are 72, 36, 18, 47
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(72, 36) = 72
GCD(72, 36) = ( 72 x 36 ) / 72
= 72 / 36
= 72
Step2:
LCM(36, 18) = 36
GCD(36, 18) = ( 36 x 18 ) / 36
= 36 / 18
= 36
Step3:
LCM(18, 47) = 846
GCD(18, 47) = ( 18 x 47 ) / 846
= 18 / 47
= 18
So, Greatest Common Divisor of 72, 36, 18, 47 is 1
