Question

Define the following
1. Natural numbers
2. Even numbers
3. Odd numbers
4. Prime numbers
5. Composite numbers
6. L C M
7. H C F
8. Write the prime factors of 25 and 100​

Answer 1

Answer:

Answers:

1. Natural Numbers : The positive integers (whole numbers) 1, 2, 3, etc., and sometimes zero as well.

2. Even Numbers : A number which is divisible by 2 and generates a remainder of 0 is called an even number.

3. Odd numbers : An odd number is a number which is not divisible by 2. The remainder in the case of an odd number is always “1”.

4. Prime Numbers : A number that is divisible only by itself and 1 (e.g. 2, 3, 5, 7, 11).

5. Composite Numbers : A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.

6. L.C.M : L.C.M. defines the least number which is exactly divisible by two or more numbers.

7. H.C.F : HCF or Highest Common Factor of two or more numbers is the greatest factor that divides the numbers. For example, 2 is the HCF of 4 and 6.

8. Prime Factors for 25: 5 and 5. Prime Factors for 100: 2, 2, 5, and 5.

Answer 2

Answer:

Natural numbers-The positive integers(whole number).1,2,3 etc and sometimes zero as well

Even number-The number which IS divisible by 2

Odd number-Odd numbers are whole number that cannot be divided exactly into pairs

Prime number-The number that is only divisible by itself and one

Composite numbe-whole number that taht have more than two factors

L.C.M-Least common multiple

H.C.F-Highest common factor
