GCF/LCM

September 16, 2016 — Leave a comment

This method is known as “The Ladder Method”

Take two numbers, (i.e. 216 and 144) and put them on an “L” shape

mathstep2

Now, on the left of the “L”, divide the two numbers by the lowest prime factor

mathstep3

Write the quotients below, and do the same for them

mathstep4mathstep5

Repeat the process until you have two prime numbers left

mathstep6

To find the LCM (432), multiply all of the numbers on the outside and bottom of the ladder

mathstep7

To find the GCF (72), multiply only the left outside of the ladder

mathstep8

 

I prefer the method of finding the LCM and GCF with prime factorization through the division table.

Bubblegum Lab

Conclusion:

Hubba Bubba is best for blowing bubbles as it is thicker and more durable, which allows it to withstand more pressure. It’s like that due to it starting all as one piece, compared to the Big League Chew which is lots of small pieces, because the one piece will be connected better rather than the Big League Chew which will have a weaker connection due to it being many pieces mashed together.

Measuring the bubble.
