Factors of 150
The factors of 150 are numbers that divide 150 evenly without leaving any remainder. They appear in pairs, for instance, (1, 150), (-1, -150), and so on. Both positive and negative pairs exist, such as (-1, -150). These factors are always whole numbers. You can determine them by dividing 150 by smaller integers or by using prime factorization. Knowing the factors of 150 is important for understanding divisibility rules, multiples, and prime properties. Below, we’ll go through all factors, factor pairs, and the prime factorization of 150 step by step.
What are the Factors of 150?
When we talk about the factors of 150, we’re referring to numbers that divide it evenly. These are 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75 and 150. If we also consider negative divisors, we get -1, -2, -3, -5, -6, -10, -15, -25, -30, -50, -75 and -150. Each factor pairs with another to make 150. This idea of factorization is key in number theory, it tells us whether 150 is prime or composite. Because 150 has several factors, it’s classified as a composite number, meaning it is built from smaller integers.

Factor Pairs of 150
Factor pairs of 150 are pairs of numbers that, when multiplied, result in 150. These pairs come in both positive and negative forms. For example, the positive pairs are (1, 150), (2, 75), (3, 50), (5, 30), (6, 25), (10, 15), and the negative ones are (-1, -150), (-2, -75), (-3, -50), (-5, -30), (-6, -25), (-10, -15). Recognizing these pairs helps you see how 150 is structured mathematically and improves understanding of how numbers relate through multiplication and division. This concept is also helpful when finding the greatest common factor or simplifying fractions. 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 150?
Finding the factors of 150 can be done efficiently using the division method. You only need to check numbers up to the square root of 150, because each divisor below the square root has a matching pair above it. Each number that divides 150 evenly forms a factor pair, giving you both the divisor and its corresponding factor. This method saves time and helps understand the structure of 150 in terms of its building blocks.
Optimized steps to find factors of 150:
- •150 ÷ 1 = 150 → ✅ Factor Pair: (1, 150)
- •150 ÷ 2 = 75 → ✅ Factor Pair: (2, 75)
- •150 ÷ 3 = 50 → ✅ Factor Pair: (3, 50)
- •150 ÷ 5 = 30 → ✅ Factor Pair: (5, 30)
- •150 ÷ 6 = 25 → ✅ Factor Pair: (6, 25)
- •150 ÷ 10 = 15 → ✅ Factor Pair: (10, 15)
This method avoids unnecessary checks and quickly identifies all factor pairs, making it especially helpful for larger numbers.
