This method works for two numbers

Explanation:

write 24/124 as smallest possible fraction.
So 24/124 becomes 12/62 and then 6/31.
6/31 is the smallest possible fraction.
now take the denominator(i.e, 31) and multiply with 24 or other way around , you can take numerator ( i.e,6) and multiply with 124.

So, the answer would be 2431 = 6124 = 744.
hope this helps!

See steps and process below;

Explanation:

Finding the Least Common Multiple of 24 and 124 you need to find the common factors of the given digits..

24 = 2 xx 2 xx 2 xx 3

124 = 2 xx 2 xx 31

Recall the common digits!

Which are;

24 = color(red)(2 xx 2) xx 2 xx 3

124 = color (red)(2 xx 2) xx 31

Please note that the ones in color shouldn't be repeated but be written once..

Hence the common multiple is as follows;

LCM: 2 xx 2 xx 3 xx 31 = 372

Hence the LCM of 24 and 124 is 372
