Best Answer

it's simple, you divide the potential factor by the original number.

For example, if I wanted to find out if 12 was a factor of 36;

36/12= 3

Because this number is an integer and not a decimal we know that in fact, 12 is a factor of 36.

I hope that helped :)

How can you test to determine whether a number is a factor of another numberr?

Divide the smaller number into the bigger number. If the answer comes out even with no remainder, it's a factor.


How can you test to determine whether a number is a factor of another number?

Divide the larger number by the smaller. If the result has no remainder (no decimal) then the smaller number is a factor of the larger.


How can you test to determine if a factor is a factor of another number?

Divide the factor into the number. If the answer is a whole number, the factor is a factor.


How do you find the 12th prime number using c?

To keep it simple: Write a main loop that goes through all the numbers, starting with 2, and incrementing one at a time. Determine whether each number is a prime number. If it is, increment a counter. To determine whether each number is a prime number, either use an inner loop, or a separate function. Test divisibility of the number "n" by every number from 2 to n-1. If you find a factor, then it is not a prime number. Note that you can test divisibility by using the "%" operator. For example: if (number % factor == 0) // number is divisible by factor else // it isn't


How do you determine whether a number is a factor of another number?

If N is the number, and f is the number that you want to test as a possible factor, then first of all:test N > f (this must be true, the factors are always smaller in magnitude)next perform N ÷ f (N divided by f). If the quotient (answer to a division problem) is a whole number with no remainder or fractional part, then f is a factor of N.If the quotient is not a whole number (meaning there is a remainder), then f is not a factor.

How can you determine if a number is a prime number?

if it has no other number that can divide into itself but itself ================================== Another contributor clarified: You have to determine whether there is any number ... besides '1' and the number under test itself ... that can divide evenly into the number under test. If you find even one, then it's not a prime. If there are none, then it's a prime.
