To find all factor pairs of 10, we check integers starting from 1: 1 × 10 = 10 and 2 × 5 = 10. Thus, the positive factors of 10 in ascending order are 1, 2, 5, and 10.

factors of factors of 2 3 5 10 level

Answer: Factors of 2: 1, 2; Factors of 3: 1, 3; Factors of 5: 1, 5; Factors of 10: 1, 2, 5, 10

Step-by-step solution

Step 1: Define what a factor is

A factor of a number is an exact divisor of that number. Every non-zero whole number has at least $1$ and itself as factors.

Step 2: Find the factors of prime numbers 2, 3, and 5

The numbers $2$ , $3$ , and $5$ are prime numbers. By definition, a prime number has exactly $2$ distinct positive factors: $1$ and the number itself.

Step 3: Find the factors of composite number 10

To find all factor pairs of $10$ , we check integers starting from $1$ : $1 \times 10 = 10$ and $2 \times 5 = 10$ . Thus, the positive factors of $10$ in ascending order are $1$ , $2$ , $5$ , and $10$ .
