# divisor

noun (divisor, divisors)

«divisor» in the English dictionary: everyday — its meanings, how the lessons use it, and examples, each with its tree on Mova.

## Everyday

1. A divisor is the number you divide by. In 12 ÷ 3, the divisor is 3. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/D/divisor/#m1)
2. A divisor of a number is also a number that divides it exactly with no remainder; 3 is a divisor of 12. It is also called a factor. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/D/divisor/#m2)

### In the lessons

In maths: the number divided by; names a part of division: dividend ÷ divisor = quotient, and number = divisor × quotient (+ remainder); the remainder is always smaller than the divisor; greatest common divisor of two numbers. Phrases: common divisor, greatest common divisor, divisor of.

### Examples

- In 20 ÷ 4 = 5 the divisor is 4. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/D/divisor/#x1)
- List all divisors of 12. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/D/divisor/#x2)
- The greatest common divisor of 8 and 12 is 4. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/D/divisor/#x3)
- The divisor is 6 and the quotient is 7. What is the number? [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/D/divisor/#x4)
- 1 is a divisor of every whole number. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/D/divisor/#x5)
- 7 has only two divisors, 1 and 7, so it is a prime number. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/D/divisor/#x6)
- The remainder must be less than the divisor. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/D/divisor/#x7)
- Is 5 a divisor of 32? [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/D/divisor/#x8)

### Note

Parts of division: dividend ÷ divisor = quotient. «Divisor» and «factor» often mean the same. Names a part of division: number = divisor × quotient (+ remainder). Trap: the divisor is not the answer. Trap: you can never divide by zero, so 0 is never a divisor.
