Factors of 112
The factors of 112 are integers that divide 112 completely, leaving no remainder. These factors can be positive or negative and usually come in pairs like (1, 112) and (-1, -112). Finding factors helps you understand how numbers are built and related to each other. You can discover the factors of 112 by testing smaller numbers or using prime factorization methods. Learning this concept is useful for topics such as multiples, least common multiples (LCM), and prime numbers. Here, you’ll find all factors, factor pairs, and the prime factorization of 112 explained simply.
What are the Factors of 112?
Factors of 112 are the numbers that divide it perfectly, leaving no remainder. The positive factors are 1, 2, 4, 7, 8, 14, 16, 28, 56 and 112, and if we include negatives, we get -1, -2, -4, -7, -8, -14, -16, -28, -56 and -112. Each factor fits into 112 an exact number of times. Understanding factors helps identify whether a number is simple like a prime, or made up of smaller parts like a composite. 112 is composite because it’s made from the multiplication of smaller whole numbers.

How to Find the Factors of 112?
To determine the factors of 112, you can use an optimized division approach. By dividing 112 by integers up to its square root, you can quickly find all positive factor pairs. Every divisor found has a partner that multiplies with it to give 112, helping visualize the number's composition. This approach is especially helpful for learning multiplication, division, and number theory concepts.
Optimized steps to find factors of 112:
- •112 ÷ 1 = 112 → ✅ Factor Pair: (1, 112)
- •112 ÷ 2 = 56 → ✅ Factor Pair: (2, 56)
- •112 ÷ 4 = 28 → ✅ Factor Pair: (4, 28)
- •112 ÷ 7 = 16 → ✅ Factor Pair: (7, 16)
- •112 ÷ 8 = 14 → ✅ Factor Pair: (8, 14)
This method avoids unnecessary checks and quickly identifies all factor pairs, making it especially helpful for larger numbers.
