No because the digital sum of 143 is 8 and so therefore 9 is not a factor of 143
There isn't an easy test for 7. You have to divide it. 7 is not a factor of 291.
Answer: You check to see if fraction written in simplest form if you can't divide it by the Greatest Common Factor anymore.
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.
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.
as you can obviously see the bottom of a factor tree would be the curious numbers of 2,2,3,5
Divide it. It isn't.
I would divide it. It doesn't come out even. It's not a factor.
Divide 7 into 29. If the answer is an integer with no remainder, it's a factor.

Divide 7 into 291. If it comes out evenly, it's a factor. It doesn't, so it's not.
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.
The Highest Common Factor (HCF) of 52, 143, and 169 is 13. To find the HCF, you need to determine the prime factors of each number. The prime factors of 52 are 2^2 * 13, the prime factors of 143 are 11 * 13, and the prime factors of 169 are 13^2. The HCF is the product of the common prime factors raised to the lowest power, which in this case is 13.
No. If you divide 291 by 12 you will see that it does not go in 291 an exact number of times.
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.

Well, isn't that a happy little math problem! Let's see, if we take 143 and divide it by 20, we find that it goes in 7 times with a remainder of 3. Remember, there are no mistakes in math, only happy little accidents.
