No because the digital sum of 143 is 8 and so therefore 9 is not a factor of 143

How would you tested to see weather 7 is a factor of 291?
There isn't an easy test for 7. You have to divide it. 7 is not a factor of 291.
How can you check to see if fraction written in simplest form?
Answer: You check to see if fraction written in simplest form if you can't divide it by the Greatest Common Factor anymore.
What is 6 over 50 in simplest form?
See if you can find a common factor. (Hint: in this case, there is indeed a common factor.) Divide both numbers by this common factor to get an equivalent fraction.
How do you simplify fractions such as 32 over 45?
If you can find any common factor of the numerator and denominator, divide each of them by it. 32 and 45 have no common factor (except ' 1 '), so 32/45 is the simplest form. 64 and 90 have the common factor of 2. So if you see 64/90, divide the top and bottom both by 2, and you get 32/45, which is the simplest form.
How do you turn 3 percent into a fraction?
Take your percentage number and divide it by 100. So in your case, writing 3% as a fraction, you would get 3/100. If you have 50%, as a fraction you'll have 50/100. Here we see that 50 is a common factor of both 50 and 100, so we can divide both numbers by 50, getting 1/2.
How would you test to see whether 7 is as factor of 291?
Divide it. It isn't.
How will you test to see whether 7 is a factor or 291?
I would divide it. It doesn't come out even. It's not a factor.
How would you test to see whether 7 is a factor of 29?
Divide 7 into 29. If the answer is an integer with no remainder, it's a factor.
How would you tested to see weather 7 is a factor of 291?
There isn't an easy test for 7. You have to divide it. 7 is not a factor of 291.
How can you check if 7 is a factor of 291?
Divide 7 into 291. If it comes out evenly, it's a factor. It doesn't, so it's not.
How would you test if 7 is a factor of 291?
Divide 291 by 7 and see if you get a whole number or is there a remainder. If it is not a whole number, then it is not a factor. 7 goes into 291 41 times with a remainder of 4, so it is not a factor.
Is 12 a factor of 291?
No. If you divide 291 by 12 you will see that it does not go in 291 an exact number of times.
Is 13 a factor of 179?
No, 13 is not a factor of 179. One way to tell is to divide 179 by 13, the quotient is not a whole number, so it is not a factor. Another way to tell is to see that 13 times thirteen is 169, so if 179 were a factor it would be 13 away from 169. Since 179 minus 169 is 10, 179 is not a factor.
How can you check to see if fraction written in simplest form?
Answer: You check to see if fraction written in simplest form if you can't divide it by the Greatest Common Factor anymore.
What is 6 over 50 in simplest form?
See if you can find a common factor. (Hint: in this case, there is indeed a common factor.) Divide both numbers by this common factor to get an equivalent fraction.
What fraction is equivalent to eight twelves?
See if you can find a common factor between the two numbers. Then divide top and bottom of the fraction by this common factor.
When would you use a factor tree?
Factor trees are useful when you need to see the factors of a number. It is sometimes easier to see everything spread out.
