Factors of 24
In mathematics, factors of 24 are numbers that multiply together to make 24. For example, 1 × 24 = 24, so both 1 and 24 are factors. Every number has at least two factors: 1 and itself. These factors always divide 24 completely without leaving a remainder. To find them, you can use basic division or break the number into prime factors. Learning about the factors of 24 helps with understanding multiplication, greatest common factors (GCF), and prime factorization. Let’s explore all the factors, factor pairs, and prime factors of 24 with clear examples.
What are the Factors of 24?
Factors of 24 are the numbers that divide it perfectly, leaving no remainder. The positive factors are 1, 2, 3, 4, 6, 8, 12 and 24, and if we include negatives, we get -1, -2, -3, -4, -6, -8, -12 and -24. Each factor fits into 24 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. 24 is composite because it’s made from the multiplication of smaller whole numbers.

Factor Pairs of 24
When two numbers multiply to give 24, they form a factor pair. The positive factor pairs of 24 are (1, 24), (2, 12), (3, 8), (4, 6), and the negative ones are (-1, -24), (-2, -12), (-3, -8), (-4, -6). Each pair demonstrates how 24 can be created by multiplying two integers. Learning about factor pairs is useful in arithmetic and algebra. It helps in understanding divisibility, simplifying problems, and working with greatest common factors and prime numbers. You can also explore how factor pairs relate to the greatest common factor and prime factorization for deeper understanding.

How to Find the Factors of 24?
To determine the factors of 24, you can use an optimized division approach. By dividing 24 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 24, 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 24:
- •24 ÷ 1 = 24 → ✅ Factor Pair: (1, 24)
- •24 ÷ 2 = 12 → ✅ Factor Pair: (2, 12)
- •24 ÷ 3 = 8 → ✅ Factor Pair: (3, 8)
- •24 ÷ 4 = 6 → ✅ Factor Pair: (4, 6)
This method avoids unnecessary checks and quickly identifies all factor pairs, making it especially helpful for larger numbers.
