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
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:
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
