Examples on Multiples of 77

Simple Multiples

• 77: 77 × 1 = 77
• 154: 77 × 2 = 154
• 231: 77 × 3 = 231

Larger Multiples

• 770: 77 × 10 = 770
• 1540: 77 × 20 = 1540
• 2310: 77 × 30 = 2310

Real-Life Examples

• Distance: 154 kilometers is a multiple of 77 because 77 × 2 = 154.
• Time: 1540 minutes is a multiple of 77 because 77 × 20 = 1540.
• Area: A plot of land that is 2310 square meters is a multiple of 77 because 77 × 30 = 2310.

Practical Examples of Multiples of 77

1. Distance: A marathon is approximately 42 kilometers, which is not a multiple of 77. However, if a race is 154 kilometers, it is a multiple of 77 because 77 × 2 = 154.
2. Time: Suppose an event lasts 1540 minutes. This duration is a multiple of 77 because 77 × 20 = 1540, showing how multiples of 77 can be used in scheduling.
3. Area: Consider a rectangular field with an area of 2310 square meters. This is a multiple of 77, as 77 × 30 = 2310, which is useful in land measurement and planning.
4. Travel: A bus route that covers 770 kilometers is a multiple of 77 because 77 × 10 = 770. This helps in calculating long distances in travel planning.
5. Construction: If a construction project uses 4620 bricks, it is a multiple of 77 since 77 × 60 = 4620. This illustrates how multiples of 77 can be practical in resource estimation.

Practical Applications

• Counting by Seventy-Sevens: When counting by seventy-sevens (77, 154, 231, 308…), you are listing the multiples of 77.
• Identifying Multiples: Any multiple of 77, such as 154 or 231, follows the pattern 77 × n, where n is an integer. For example, 154 is a multiple of 77 because 77 × 2 = 154.

Is 462 a multiple of 77?
