What two numbers make 440?
Factor pairs: 440 = 1 x 440, 2 x 220, 4 x 110, 5 x 88, 8 x 55, 10 x 44, 11 x 40, or 20 x 22.
What two numbers make 375?
The pair of numbers that give 375 when multiplied with each other is called the factor pairs of 375.
- 375 = 1 × 375.
- 375 = 3 × 125.
- 375 = 5 × 75.
- 375 = 15 × 25.
- Therefore, the factor pairs of 375 are (1, 375), (3, 125), (5, 75), and (15, 25).
- Since the product of two negative numbers is positive, i.e. (-) × (-) = (+).
What is the 1089 Trick?
Here’s a cool mathematical magic trick. Write down a three-digit number whose digits are decreasing. Then reverse the digits to create a new number, and subtract this number from the original number. With the resulting number, add it to the reverse of itself. The number you will get is 1089!
Why is 1089 a magic number?
1089 is widely used in magic tricks because it can be “produced” from any two three-digit numbers. This allows it to be used as the basis for a Magician’s Choice. Take any three-digit number where the first and last digits differ by more than 1.
