Factoring is a basic math concept that has many practical uses, but often people don't even realize they are factoring!
\(=4\times\)
\(=20\times \)
\(=10\times \)
\(= 4 \times\)
\(=2\times \)
Have you ever considered how information is kept secure when sent electronically?
If two very large numbers are multiplied together, it is very difficult to find the original two numbers of the product.
Factoring can also be used to plan trips. Consider travelling \(500\) km.
\(5 \text{ h} \times 100 \text{ km/h}\)
\(500 \text{ km} =\)
\(10 \text{ h} \times 50 \text{ km/h}\)
\(20 \text{ h} \times 25 \text{ km/h}\)
If a number is a multiple of \( 4 \),what else might be true about the number?
