FAQs on Flashcards: Factors and Multiples Flashcard - Mathematics for Class 4

1. What are the differences between factors and multiples?
Ans.Factors are the numbers that can be multiplied together to get another number, whereas multiples are the results of multiplying a number by an integer. For example, factors of 12 are 1, 2, 3, 4, 6, and 12, while the multiples of 3 include 3, 6, 9, 12, 15, and so on.
2. How do you find the factors of a number?
Ans.To find the factors of a number, start with 1 and the number itself, then test all integers up to its square root. If a number divides evenly into the target number, both the divisor and the quotient are factors.
3. How do you determine the least common multiple (LCM) of two numbers?
Ans.To find the LCM of two numbers, list the multiples of each number until you find the smallest multiple that they both share. Alternatively, you can use the prime factorization method or the formula: LCM(a, b) = (a * b) / GCD(a, b), where GCD is the greatest common divisor.
4. Why are factors and multiples important in mathematics?
Ans.Factors and multiples are foundational concepts in mathematics that aid in understanding division, fractions, and algebra. They are also essential for solving problems related to ratios, proportions, and finding common denominators.
5. Can a number be both a factor and a multiple of another number?
Ans.Yes, a number can be both a factor and a multiple of another number. For example, the number 6 is a factor of 12 and also a multiple of 3.
