## What are the factors of 998?

The factors of 998 are 1, 2, 499, 998.

## How do you find the factors?

To calculate the factors of large numbers, divide the numbers with the least prime number, i.e. 2. If the number is not divisible by 2, move to the next prime numbers, i.e. 3 and so on until 1 is reached. Below is an example to find the factors of a large number.

**What are the factors for 850?**

Factor Pairs of 850

- 1 x 850 = 850.
- 2 x 425 = 850.
- 5 x 170 = 850.
- 10 x 85 = 850.
- 17 x 50 = 850.
- 25 x 34 = 850.

**How many factors does a prime number have?**

two factors

A prime number is a counting number that only has two factors, itself and one. Counting numbers which have more than two factors (such as 6, whose factors are 1, 2, 3, and 6), are said to be composite numbers.

### What is the prime factorization of 999?

The Prime Factors and Pair Factors of 999 are 3 × 37 and (1, 999), (3, 333), (9, 111), (27, 37) respectively.

### Which has only one factor?

1 is the only number which has only single factor, that is, 1 itself.

**What’s a factor in math?**

factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.

**What are the factors of 650?**

Factors of 650

- All Factors of 650: 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325 and 650.
- Prime Factors of 650: 2, 5, 13.
- Prime Factorization of 650: 21 × 52 × 131
- Sum of Factors of 650: 1302.

#### How do you find primes?

To prove whether a number is a prime number, first try dividing it by 2, and see if you get a whole number. If you do, it can’t be a prime number. If you don’t get a whole number, next try dividing it by prime numbers: 3, 5, 7, 11 (9 is divisible by 3) and so on, always dividing by a prime number (see table below).

#### What is a number that goes into a greater number with no remainders called?

Finding the factors of a natural number means that you find all the possible numbers that will divide into the given number without a remainder. There are many rules of divisibility to help you to find factors more quickly. A prime number is a number that has exactly two factors.
