If you prime factorize a number and you use the ladder method why do you always have to divide by prime numbers?

It's more efficient. You want to end up with all prime numbers. You could divide by a composite number, but you'd just have to break that number down later. It saves steps.

A 15 foot ladder is leaning against a 30 foot wall The bottom end of the ladder is 9 feet from the wall How many feet above the ground does the ladder touch the wall?
12 feet. It is actually pretty easy, if you remember that a 3x4x5 triangle is always a right angle. divide by 3 and you have the 3 and 5 all you need is the four multiplied by 3.
Is there a compound word with ladder in it?
step ladder
What is the division ladder what is the GCF of 82?
The division ladder is a method used to find the greatest common factor (GCF) of two numbers by listing the factors of each number. To find the GCF of 82, you would start by factoring the number 82. The factors of 82 are 1, 2, 41, and 82. Therefore, the GCF of 82 is 1.
The base of a ladder is 7 feet away from the wall The top of the ladder is 19 feet from the floor Find the length of the ladder to the nearest thousandth?
Using Pythagoras' theorem the length of the ladder is 20.248 feet
How many steps does a ladder have?
A ladder has different amount of steps, depending on how big it is.

What are the rungs of the steps DNA ladder made of?
The 'steps' or 'rungs' of the DNA 'ladder' are complimentary pairs of bases bonded by hydrogen bonds. The bases are Adenine, Thymine, Cytosine and Guanine. Adenine always bonds to Thymine and Cytosine always bonds to Guanine.

A boat has a rope ladder attached to it. The ladder goess 1 foot into the water. It starts to rain. It rains 1 inch of water per 45 mins. How long will it take until the ladder is 3 ft into the water?
The boat rises as the water rises so the ladder will always be 1 foot in the water.

The part of the twisted ladder or double helix of DNA is made for the nucleotide bases are adenine always pairs up with thymine on the other side, guanine always pairs up with cytosine.
What is the ladder method?
It's a method that lets you quickly find both the greatest common factor and the least common multiple of two numbers. I am not sure how well it works for more than two numbers at a time. If you search online for "ladder method", you'll quickly find several videos that show you how to do it.
