Steps to Calculate GCD of 29, 81, 90, 54 using LCM Formula
Given numbers are 29, 81, 90, 54
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(29, 81) = 2349
GCD(29, 81) = ( 29 x 81 ) / 2349
= 29 / 81
= 29
Step2:
LCM(1, 90) = 90
GCD(1, 90) = ( 1 x 90 ) / 90
= 1 / 90
= 1
Step3:
LCM(1, 54) = 54
GCD(1, 54) = ( 1 x 54 ) / 54
= 1 / 54
= 1
So, Greatest Common Divisor of 29, 81, 90, 54 is 1
