240240

Explanation:

Here we go..

For Lowest Common Multiple

First you need to find each multiple..

The common multiple should be represented singly..

For example

We have; 2 and 82and8

Factors of 2 = 22=2

Factors of 8 = 2 xx 48=2×4

Since 22 is a common multiple for both, we represent it as a single 22

Hence we have the Least Common Multiple of 2 and 82and8 as 2 xx 4 = 82×4=8

Now regarding the question..

We have 5, 8 and 125,8and12

Finding the multiples...

Factors of 5 = color(red)55=5

Factors of 8 = color(blue)2 xx color(red)48=2×4

Factors of 12 = color(blue)2 xx color(red)2 xx color(red)312=2×2×3

Since we have 22 common in both multiple, we represent it as a single 22

Hence we have rArr color(blue)2 xx color(red)2 xx color(red)3 xx color(red)4 xx color(red)5 = 2402×2×3×4×5=240

For Lowest Common Multiple

11 is the Least Common Factor, for every number based on what is asked..

Which ever way, you choose either it is the Lowest Common Multiple (LCM) or the Lowest Common Factor which is above..

You can choose from anyone..

Why 22 is not the lowest common factor because it 55 cannot be divided by 22..
