Factor them.
2 x 2 x a = 4a
2 x 5 x a x a = 10a2
Combine the factors, eliminating duplicates.
2 x 2 x 5 x a x a = 20a2, the LCM
Finding an LCM will help when you want to add and subtract fractions.
If the first step is writing down the numbers, the second step is finding their prime factorizations.
Ah, isn't finding the least common multiple a joyous journey? The LCM of 4x and 3x is simply 12x, my friend. Just like painting a happy little tree, finding the LCM brings harmony and balance to your mathematical landscape.
It is the same as finding the LCM of two numbers that have been expressed as a product of their prime factors except that you need to use the highest index for each prime factor.
By finding out whether they have any factors in common. If the only factor they have in common is 1, the LCM will be their product. If they have more factors in common, their LCM will be less than their product.
