Factorisation

What is Factorisation?

When we break a number or a polynomial into a product of many factors of other polynomials, which, when multiplied, gives the original number, it is called factorisation.

To factorise a number, we use the factorisation formula. The factorisation is the process of converting one entity (for example, a number, or a polynomial) into a product of another entity, or factors, which, when multiplied together, yield the original number.

The factorisation formula divides a large number into smaller numbers, known as factors. A factor is a number that divides a given integer completely without leaving any remainder.

For example -  Prime Factorisation of $28=2\times 2\times 7$ and

Before starting factorisation, let us know the term, ‘Factor’.

What is a Factor?

Factors are the numbers, algebraic variables or an algebraic expression which divides the number or an algebraic expression without leaving any remainder.

For example factor of $9$ is $1,3,9$
