Factors of 200
The factors of 200 are whole numbers that divide it exactly without leaving a remainder. They appear in positive and negative pairs, like (1, 200) or (-1, -200), and are always integers, never fractions or decimals. You can find them using methods such as division or prime factorization. Learning about factors helps build a foundation for understanding divisibility, multiples, and prime numbers. In this guide, we'll explore the different types of factors of 200, including all positive factors, factor pairs, and the prime factorization of 200 with step-by-step explanations and examples.
What are the Factors of 200?
There are 12 factors of 200. The factors of 200 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100 and 200. Factors can be negative. The negative factors are -1, -2, -4, -5, -8, -10, -20, -25, -40, -50, -100 and -200. All of these numbers divides 200 completely. 200 is a composite number because it has other factors besides 1 and 200.

How to Find the Factors of 200?
To find the factors of 200 using the division method efficiently, you only need to check numbers up to the square root of 200. For every number that divides 200 evenly, both it and its corresponding pair (200 ÷ that number) are factors.
Optimized steps to find factors of 200:
- •200 ÷ 1 = 200 → ✅ Factor Pair: (1, 200)
- •200 ÷ 2 = 100 → ✅ Factor Pair: (2, 100)
- •200 ÷ 4 = 50 → ✅ Factor Pair: (4, 50)
- •200 ÷ 5 = 40 → ✅ Factor Pair: (5, 40)
- •200 ÷ 8 = 25 → ✅ Factor Pair: (8, 25)
- •200 ÷ 10 = 20 → ✅ Factor Pair: (10, 20)
This method avoids unnecessary checks and gives all factor pairs quickly. It's especially useful for larger numbers.
