GCF is the Greatest Common Factor. It would be the largest number that can divide evenly into all the numbers you need to find the GCF in.
exapmple GCF for 12 and 16
12: 1, 2, 3, 4, 6, 12
16: 1, 2, 4, 8, 16
the largest common number is 4, so 4 is the GCF of 12 & 16
LCM = Least Common Multiple is the smallest number ( other than zero) that is a multiple of both
LCM of 3 and 5
3: 3, 6, 9, 12, 15, 18
5: 5, 10, 15, 20
the first common number is 15, so this is the LCM of 3 & 5
Slope:

46% / 100% = ?/ 200 ⇒ you can say 100 ×2 = 200 so 46 ×2 = 92 so the answer is 92 :D
Unknown side length of two similar triangles can be found out by scale factor and any of the side lengths.
Step-by-step explanation:
The similarity is one of the criteria of triangles. Two triangles are similar when their respective sides are in similar ratio or proportion. In layman’s term, it can be understood as a condition in which two triangles have similar shapes but not similar sizes.
If ΔABC is similar toΔ XYZ, then their respective sides would be in proportion to each other.
This means AB/XY=AC/XZ=BC/YZ
This common ratio is often termed as “scale factor”
Hence any sides length can be found out if either of the terms (i.e. scale factor, side ) is given.
