Factor Pairs Explained:A Simple Guide to Multiplying Numbers

Af Eric Tosso | Opdateret 30. august 2022

Hvad er et naturligt tal?

A natural number is any positive integer—whole numbers greater than zero. Tal som 1, 28, 100 er naturlige; 28,5 eller -3 er det ikke.

Forstå multiplikation

Multiplication combines two or more numbers to produce a product. For example, 2 × 3 =6, where 6 is the product of 2 and 3.

Definition af en faktor

En faktor er et tal, der deler et andet tal uden at efterlade en rest. I produktet 5 × 6 =30 er tallene 5 og 6 faktorer på 30.

Identifikation af faktorpar

Every natural number can be expressed as a product of at least one pair of factors. For eksempel:

• 17 har kun ét faktorpar:1 og 17.
• 28 can be factored as 1 × 28, 2 × 14, and 4 × 7.

Each pair of numbers that multiplies to a specific product is called a factor pair. Prime numbers, like 17, have only the trivial pair 1 and itself.
