Factor out the 6, 6*1 : 6*7 as 6 appears in both sides of this ratio as a factor it can be eliminated 1 : 7 ===
Well, let's take a look at this happy little math problem. A factor is a number that can be multiplied to get another number. In this case, 6 divided by 42 leaves a remainder, so 42 is not a factor of 6. Just remember, there are no mistakes in math, just happy little accidents!
42
Impossible
The highest common factor of 6 & 7 is 1
7
The GCF of 6, 7, and 28 is 1.
The lowest common factor of 6, 4 and 7 is 84.
1, 2, 3, 61, 7
7 x 6 = 42
6 is the highest common factor 6*7 = 42 6*9 = 54
6 is not.
