Introduction

In mathematics, a factor is a whole number that divides another number exactly without leaving a remainder. In this article, we will explore the factors of 385, a positive integer that can be expressed as the product of prime numbers. We will list all the factors of 385 in ascending order and provide a detailed explanation of the process involved.

What are Factors?

Factors are the building blocks of numbers. They are the numbers that can be multiplied together to get another number. For example, the factors of 6 are 1, 2, 3, and 6, because 1 × 2 × 3 = 6. Factors can be prime or composite numbers.

Prime Factorization of 385

To find the factors of 385, we need to find its prime factorization. Prime factorization is the process of expressing a number as the product of prime numbers. The prime factorization of 385 is:

385 = 5 × 7 × 11
