Steps to Calculate GCD of 54, 75, 28, 12 using LCM Formula
Given numbers are 54, 75, 28, 12
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(54, 75) = 1350
GCD(54, 75) = ( 54 x 75 ) / 1350
= 54 / 75
= 54
Step2:
LCM(3, 28) = 84
GCD(3, 28) = ( 3 x 28 ) / 84
= 3 / 28
= 3
Step3:
LCM(1, 12) = 12
GCD(1, 12) = ( 1 x 12 ) / 12
= 1 / 12
= 1
So, Greatest Common Divisor of 54, 75, 28, 12 is 1
