Important Notes

Definition of Multiples

• A multiple of a number is the product of that number and an integer.
• For example, the multiples of 105 are obtained by multiplying 105 by integers: 105×1 = 105, 105×2 = 210, 105×3 = 315, and so on.

Properties of Multiples of 105

• Divisibility: Every multiple of 105 is divisible by 105, 5, 7, and 3 (since 105=3×5×7105 = 3 \times 5 \times 7105=3×5×7).
• Common Multiples: Multiples of 105 can also be considered common multiples of 3, 5, and 7.

First Few Multiples of 105

The first few multiples of 105 are:

• 105 (105 × 1)
• 210 (105 × 2)
• 315 (105 × 3)
• 420 (105 × 4)
• 525 (105 × 5)

Recognizing Multiples of 105

A number is a multiple of 105 if:

• It ends in 0 or 5 (divisible by 5).
• The sum of its digits is divisible by 3.
• The number is divisible by 7.

For example, 210:

• Ends in 0 (divisible by 5).
• Sum of digits: 2 + 1 + 0 = 3 (divisible by 3).
• Divisible by 7 (210 ÷ 7 = 30).

Applications of Multiples of 105

• LCM and GCD: Multiples of 105 are useful when finding the Least Common Multiple (LCM) and Greatest Common Divisor (GCD) involving the numbers 3, 5, and 7.
• Pattern Recognition: Recognizing patterns in multiples of 105 can simplify complex arithmetic and algebraic problems.

Examples on Multiples of 105

First Ten Multiples of 105:

• 105 × 1 = 105
• 105 × 2 = 210
• 105 × 3 = 315
• 105 × 4 = 420
• 105 × 5 = 525
• 105 × 6 = 630
• 105 × 7 = 735
• 105 × 8 = 840
• 105 × 9 = 945
• 105 × 10 = 1050

Properties and Patterns:

Additive Property: The sum of two multiples of 105 is also a multiple of 105.

• Example: 210 + 420 = 630 (both 210 and 420 are multiples of 105, and so is 630).

Subtracting Property: The difference between two multiples of 105 is also a multiple of 105.

• Example: 840 – 525 = 315 (both 840 and 525 are multiples of 105, and so is 315).

Real-world Applications:

Scheduling: If an event occurs every 105 days, the schedule can be determined using multiples of 105.

• Example: If an event starts on January 1st, the next occurrence will be on April 16th (105 days later), then on July 30th (210 days later), and so on.

Bulk Quantities: In manufacturing, ordering parts in multiples of 105 can help in inventory management.

• Example: If a factory orders screws in batches of 105, ordering 5 batches means they receive 525 screws (5 × 105).

Large Multiples:

• 105 × 20 = 2100
• 105 × 50 = 5250
• 105 × 100 = 10500
• 105 × 500 = 52500

Practical Example in Measurements:

Distance: If a car travels 105 miles in one trip, then over multiple trips, the distance covered can be calculated using multiples of 105.

• Example: Over 3 trips, the car travels 315 miles (105 × 3 = 315).
