FAQs on Factors Video Lecture - Mathematics for Class 4

1. What are factors in mathematics?
Ans.Factors are numbers that can be multiplied together to produce another number. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12 because these numbers can be multiplied in pairs to give the product of 12.
2. How do I find the factors of a number?
Ans.To find the factors of a number, you can start by dividing that number by 1 and then by each whole number up to the number itself. If the division results in a whole number (no remainder), then that divisor is a factor of the original number.
3. What is the difference between factors and multiples?
Ans.Factors are the numbers that divide another number evenly, whereas multiples are the result of multiplying a number by an integer. For example, the factors of 6 are 1, 2, 3, and 6, while the multiples of 6 include 6, 12, 18, 24, and so on.
4. Can a number have more than two factors?
Ans.Yes, a number can have more than two factors. For instance, the number 18 has six factors: 1, 2, 3, 6, 9, and 18. Numbers that have exactly two factors are called prime numbers, while numbers with more than two factors are called composite numbers.
5. Why are factors important in math?
Ans.Factors are important because they help in simplifying fractions, finding least common multiples, and solving equations. Understanding factors also lays the foundation for more advanced topics in mathematics, such as algebra and number theory.
