In this topic, let's learn about factors. It is scarce to find numbers that will divide a given number up to the smallest unit without remainder. These numbers are known as the factors, and learning about factors happens when a student comes across a number or number pair in the real world.
With the help of the long division method, we can find out that 625 can be easily divided by 1, 5, 25, 125, and 625. It is also worth remembering that numbers, having only 2 factors, are called prime numbers.
There are many methods which the students can use to find out the factors of a number. Some of the most used methods are given below.
Multiplication method is quite an easy method where we find the pair of numbers which when multiplied with each other give the desired number. For 625 the pairs are.
1×625=625
5×125=625
25×25=625
Hence, we can conclude that the factors of 625 are 1, 5, 25, 125
In the division method, you need to divide the given number 625 by every number starting from 1. If any number is able to divide it without leaving any reminder, then that number is considered as one of its factors.
625÷1=625 (no remainder)
625÷5=125 (no remainder)
625÷25=25 (no remainder)
Prime factorization is done by dividing the number by prime numbers to see which prime number is able to divide it, and if it does, then that number is considered as a prime number.
625÷5=125 (5 is a prime factor).
5 is a prime.
Therefore, prime factors of 625 is 5
A factor tree is a form of number tree, which is a diagram which represents simple division, where the number at the top is divided until it reaches a prime number or cannot be further divided.
What is the smallest number that has exactly 3 factors?
Is 22 a perfect square number?
What are the factors of 72?
