The Factoring Calculator finds the factors and factor pairs of a positive or negative number. Enter an integer number to detect its factors.

For positive integers the calculator volition only present the positive factors considering that is the normally accepted answer. For instance, you become ii and iii every bit a factor pair of 6. If y'all also demand negative factors you will need to indistinguishable the reply yourself and repeat all of the factors as negatives such as -2 and -three every bit some other cistron pair of six. On the other manus this calculator will give you negative factors for negative integers. For example, -ii and 3 AND 2 and -iii are both factor pairs of -half dozen.

Factors are whole numbers that are multiplied together to produce another number. The original numbers are factors of the product number. If a ten b = c and then a and b are factors of c.

Say you wanted to detect the factors of 16. You would detect all pairs of numbers that when multiplied together resulted in sixteen. We know 2 and eight are factors of 16 because two x 8 = sixteen. four is a cistron of 16 considering iv x 4 = 16. Also 1 and 16 are factors of 16 because ane x 16 = 16. The factors of 16 are 1, 2, 4, 8, xvi.

You can besides call back about factors in terms of sectionalization: The factors of a number include all numbers that split evenly into that number with no remainder. Consider the number 10. Since 10 is evenly divisible by 2 and 5, you lot can conclude that both 2 and 5 are factors of 10.

The table below lists the factors for 3, xviii, 36 and 48. Information technology is important to note that every integer number has at to the lowest degree two factors: ane and the number itself. If a number has just two factors that number is a prime number.

Example Factor Lists

one, ii, 3, four, 6, ix, 12, 18, 36

1, 2, three, 4, vi, eight, 12, 16, 24, 48

How to Gene Numbers: Factorization

This factors calculator factors numbers by trial division. Follow these steps to utilise trial division to find the factors of a number.

Find the square root of the integer number n and round down to the closest whole number. Permit'due south call this number southward.
Start with the number i and observe the corresponding gene pair: n ÷ 1 = n. Then 1 and n are a gene pair because division results in a whole number with naught remainder.
Do the same with the number 2 and proceed testing all integers (north ÷ 2, n ÷ 3, n ÷ four... n ÷ s) up through the square root rounded to due south. Tape the factor pairs where sectionalization results in whole integer numbers with cipher remainders.
When you reach northward ÷ southward and yous have recorded all factor pairs you accept successfully factored the number n.

Instance Factorization Using Trial Division

Factors of 18:

The square root of 18 is 4.2426, rounded downwards to the closest whole number is iv
Testing the integer values 1 through iv for division into 18 with a 0 remainder we get these gene pairs: (ane and 18), (2 and 9), (3 and 6). The factors of 18 are ane, 2, 3, half dozen, 9, 18.

Factors of Negative Numbers

All of the to a higher place information and methods mostly apply to factoring negative numbers. Just be certain to follow the rules of multiplying and dividing negative numbers to detect all factors of negative numbers. For example, the factors of -vi are (1, -6), (-1, 6), (2, -3), (-ii, 3). See the Math Equation Solver Reckoner and the section on Rules for Multiplication Operations.
