Factors of 187
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.
What are the factors of 187?
With the help of the long division method, we can find out that 187 can be easily divided by 1, 11, 17, and 187. It is also worth remembering that numbers, having only 2 factors, are called prime numbers.
How to find the factors of 187
There are many methods which the students can use to find out the factors of a number. Below you can find some of these methods.
- Multiplication method
- Division method
- Prime factors and prime factorization
- Factor tree
Finding factors using multiplication method
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 187 the pairs are.
1 × 187 = 187
11 × 17 = 187
Hence, we can conclude that the factors of 182 are 1, 11, 17, and 187.
Finding factors by division method
In the division method, you need to divide the given number 187 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.
187 ÷ 1 = 187 (no remainder)
187 ÷ 11 = 17 (no remainder)
187 ÷ 17 = 11 (no remainder)
187 ÷ 187 = 1 (no remainder)
Prime factors and prime factorization
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.
187÷11= 17 (17 is a prime factor). 11 is also a prime number. Therefore, prime factors of 187 are 11 and 17.
Factor tree
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.
Common mistakes and how to avoid them in factors of 187.
It is quite normal for students to commit a few mistakes while trying to find out the factors of a number. Below are a few such mistakes and how to avoid them
Mistake 1
Ignoring 1 and the number itself as factors.
1 and the number itself are always considered as factors since they can divide the number, leaving no reminder. Hence, students should not exclude them while listing a number of factors.
Factors of 187 Examples
Problem 1
Write the sum of prime factors of the numbers 28 and 15?
The sum of the prime factors of 28 and 15 is 19.
