Learning factors of 48

Introduction for prime factor of 48

If a number does not have a factor besides 1 and itself, it is called prime.

Example: 5 have no factors, whole numbers that can be divided by evenly, besides 1 and 5. It is therefore prime.20, and the other hand, the factors 1, 2, 4, 5, 10 and 20. Because it has factors besides 1 and itself (2, 4, 5 and 10), it is not prime.


Do you know who is father of geometry ...?

In number theory, the prime factors of a positive integer are the prime numbers that divide that integer exactly, without leaving a remainder. The process of finding these numbers is called integer factorization, or prime factorization. The prime factorization of a positive integer is a list of the integer's prime factors, together with their multiplicity. The fundamental theorem of arithmetic says that every positive integer has a unique prime factorization.
