This list was generated by our Factor Calculator. It provides a list of the factors of 1489 -
eg, the definitive answer to 1489.
This could also be described as the divisors of 1489. (we have another calculator for finding the
greatest common divisor)

These are the integers which can be evenly divided into 1489; they can be expressed as either individual factors or as factor pairs. In this case, we present them both ways. This is mathematical decomposition of a particular number. While usually a positive integer, take note of the comments below about negative numbers.

A prime factorization is the result of factoring a number into a set of components which every member is a prime number. This is generally written by showing 1489 as a product of its prime factors. For 1489, this result would be:

1489 = 1489(this is also known as the prime factorisation; the smallest prime number in this series is described as the smallest prime factor)

No! 1489 is not a composite number. None of the two factor pairs were the same number. A composite number must be formed as the product of a smaller positive integer.

No! 1489 is not a square number. The square root of this number (38.59) is not an integer.

This number has 2 factors: 1, 1489

More specifically, shown as pairs...

(1*1489) (1489*1)

The greatest common factor of two numbers can be determined by comparing the prime factorization (factorisation in some texts) of the two numbers and taking the highest common prime factor. If there is no common factor, the gcf is 1. This is also referred to as a highest common factor and is part of the common prime factors of two numbers. It is the largest factor (largest number) the two numbers share as a prime factor. The least common factor (smallest number in common) of any pair of integers is 1.

We have a least common multiple calculator here The solution is the lowest common multiple of two numbers.

A factor tree is a graphic representation of the possible factors of a numbers and their sub-factors. It is designed to simplify factorization. It is created by finding the factors of a number, then finding the factors of the factors of a number. The process continues recursively until you've derived a bunch of prime factors, which is the the prime factorization of the original number. In constructing the tree, be sure to remember the second item in a factor pair.

To find the factors of -1489, find all the positive factors (see above) and then duplicate them by adding a minus sign before each one (effectively multiplying them by -1). This addresses negative factors. (handling negative integers)

Yes.

Divisibility refers to a given integer number being divisible for a given divisor. The divisibility rule are a shorthand system to determined what is or isn't divisible. This includes rules about odd number and even number factors. This example is intended to allow the student to estimate the status of a given number without computation.
