Gamitin mo lang po ang factor tree ung 2 # na nasa pinakataas gawa ka ng number na maipagtatimes mo pababa ng pababa un.
Example: 40          20
10x4       10x2
5x2x4      5x2x2
5x2x2x2
ang least common multiple (lcm) po ay 40

For example the nos are 24 and 72 we will use:

Factor tree - look for the 2 factors 0f each no. and then slice each composite no. until you get the prime factors of the given nos then list and aline all the same nos. and if there are prime nos which do not have the same no. do not aline it with the other nos but keep it away from the others then if there are alined nos. you will bring it down as one and if your done bringing down multiply them and you'll get it.

Reapeted Division - it is just like the factor tree but you will do it in a rotated division sign and the divisor is always prime

Factor Listing - you should list all the posible multiples of the nos. and look for the least common of both given nos.
