DAV Class 5 Maths Chapter 3 Worksheet 1 Notes

• When a number divides another number exactly, then the dividend is called a multiple of the divisor.
e.g., 4 divides 32 exactly.
∴ 32 is a multiple of 4.
• When a number divides another number exactly then the divisor is called a factor.
e.g., 4 divides 12 exactly
∴ 4 is a factor of 12.
• Every number is multiple of itself.
• Every number is a multiple of 1.
• Numbers which are multiple of 2 are called even numbers.
• Numbers which are not multiples of 2 are called odd numbers.
• 1 is the common factor of any given number.
• A number that has only two factors is called a prime number.
• A number that has more than two factors is called a composite number.
