Find the greatest common factors of 45 and 60

15

Step-by-step explanation:

The GCF of 45 and 60 is 15.  

First, you have to find the factors for 60 and 45. Then find what factors 60 and 45 have in common. What is the largest factor 60 and 45 have in common?  

Factors of 45 are 1 3 5 9 15 45  

Factors of 60 are 1 2 3 4 5 6 10 12 15 20 30 60

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
