Factors Of 287 By Prime Factorization

287 is a composite number, therefore it will have prime factors. Now let’s see how to calculate the prime factors of 287. First, we will have to divide the number 287 by the smallest prime factor, which is 7. We will keep on dividing until we get a non-zero remainder.

So, by dividing 41 by 7, a non-zero remainder is obtained. Now we can stop the process and will continue dividing 41 by the next smallest prime factor. We can stop when the next prime factor doesn't exist or if we can't divide any further.

So, the prime factorization of 287 can be written as:

\begin{equation}

[71 \times 411]

\end{equation}

where 7, 41 are prime.
