How to Find Factors of 49

Now, let’s delve into the methods for finding the factors of 49 in more detail.

The Multiplication Method

One way to find the factors of 49 is through the multiplication method. This method is straightforward and involves systematically multiplying numbers until you reach 49. Here’s how it works:

  • Start with the number 1.
  • Multiply 1 by different numbers, such as 2, 3, 4, and so on, until you reach a number that, when multiplied by 1, equals 49.

By following this process, you’ll discover that the factors of 49 are 1, 7, and 49.

This method is effective for finding factors, especially for smaller numbers like 49. However, for larger numbers, it can be time-consuming, which is where prime factorization becomes a valuable technique.

The Prime Factorization Method

Prime factorization is a more systematic approach to finding factors, particularly for larger numbers. To find the factors of 49 using prime factorization, follow these steps:

  • Start by dividing 49 by the smallest prime number, which is 2. You’ll find that 49 is not divisible by 2.
  • Move on to the next prime number, which is 3. 49 is also not divisible by 3.
  • Continue this process with the next prime number, 5. Again, 49 is not divisible by 5.

Now, you might wonder why we’re focusing on prime numbers when finding the factors of 49. That’s because the prime factorization method allows us to break down 49 into its prime factors, which are the building blocks of the number.

  • Finally, we reach the prime number 7. When you divide 49 by 7, you’ll find that it’s divisible, and the result is 7.

At this point, you’ve discovered one of the factors of 49, which is 7. But what about the other factors? Well, since 7 is a prime number, it cannot be further divided into smaller prime factors. This means that 7 is a prime factor of 49, and the other factor is also 7.

So, through prime factorization, we’ve determined that the factors of 49 are 7 and 7, which can be expressed as 7² (7 squared).


In conclusion, factors of 49 are essential mathematical elements that help us understand the fundamental building blocks of numbers. The factors of 49, specifically, are 1, 7, and 49.
