Important Notes
Definition: A multiple of 30 is any number that can be expressed as 30×n, where n is an integer. This means that the multiples of 30 include numbers like 30, 60, 90, 120, and so on.
Common Factors: Multiples of 30 have common factors of 1, 2, 3, 5, 6, 10, 15, and 30. This is because 30 is the product of its prime factors 2×3×5.
Divisibility: A number is a multiple of 30 if it is divisible by both 3 and 10. To check for divisibility by 3, the sum of the digits should be divisible by 3. To check for divisibility by 10, the number must end in 0.
Pattern: The multiples of 30 follow a simple pattern where each multiple increases by 30. For example, starting from 30, the sequence is 30, 60, 90, 120, 150, etc.
Applications: Multiples of 30 are used in various practical applications such as time (minutes in an hour), measurements, and in contexts where grouping or scheduling occurs in intervals of 30 units.
