Factor them.
2 x 2 x 2 x 3 x 3 = 72
2 x 2 x 3 x 3 x 3 = 106
Combine the factors, eliminating duplicates.
2 x 2 x 2 x 3 x 3 x 3 = 216, the LCM
Least Common Multiple (LCM) for 72 108 is 216.
The LCM is: 216
The LCM is 432.
The LCM is: 216
Least Common Multiple (LCM) for 72 108 is 216
The LCM is: 216
HCF of 12 and 18 is 6 and LCM of 108 and 72 is 216 So: 6 times 216 = 1296
lcm(72, 108, 216) = 216 Using factorisation: 72 = 2³ x 3² 108 = 2² x 3³ 216 = 2³ x 3³ lcm = 2³ x 3³ = 216
Step 1 Find the prime factors of each number 36 = 2×2×3×3 = 2²×3² 72 = 2³×3² 108 = 2²×3³ Step 2 Find LCM L - Highest (Find the number with the highest exponent) C - Common (Find the common number EG. 2 and 3) M - Missing ( Take what ever is missing that is not common) LCM : 2³×3³ = 216 Your LCM is 216
The LCM of 4 and 9 is 36. Other multiples include 72 and 108.
72 and 108
Since 72 is a multiple of 36, it is automatically the LCM.
