What does it mean to say that is a divisor of A?
A divisor is a number that divides another number either completely or with a remainder. A divisor is represented in a division equation as: Dividend ÷ Divisor = Quotient. On dividing 20 by 4 , we get 5. Here 4 is the number that divides 20 completely into 5 parts and is known as the divisor.
What do u mean by a divides b?
1. “a divides b” means a and b are integers and there is an integer n, such that n x a = b; or, if you prefer b/a∈Z, or if you prefer “a divides into b evenly with no remainder”.
What does it mean to say that the integer D is a divisor of the integer n?
In more colloquial terms, to say d divides n is to say that d divides n evenly, but for us that qualification is always implied. A proper divisor d of n is a divisor of n in the range 1 1 with no proper divisors is a prime.
How do you write divided by B?
The notation “a | b” is read “a divides b”, which is a statement — a complete sentence which could be either true or false. On the other hand, “a ÷ b” is read “a divided by b”. This is an expression, not a complete sentence. Compare “6 divides 18” with “18 divided by 6” and be sure you understand the difference.
What are the divisors of 60?
Divisors of numbers

What does divisor mean in math example?
Divisor. The number we divide by. Example: in 12 ÷ 3 = 4, 3 is the divisor. Divisor can also mean: a number that divides an integer exactly (no remainder).
What does ‘a divides b’ mean?
This is what a divides b means. The shorthand notation is . Em. Em. We say a divides b, denoted by a | b, if b is a multiple of a (ie, b is an integer multiple of a ). Equivalently, a | b iff b = k a for some integer k. To remember what ” 2 divides 6 ” means, perhaps you can remember the phrase ” 2 divides 6 into 3 parts”. Hence, 2 | 6.
Is divisor a positive or negative number?
Divisor could be a positive or negative number. A number that divides an integer exactly, leaving no remainder, is also termed as the divisor. The divisor 1 and -1 can divide every integer, present in the number line. Divisors of 18
What is the number we divide by?
The number we divide by. dividend ÷ divisor = quotient Example: in 12 ÷ 3 = 4, 3 is the divisor. Divisor can also mean: a number that divides an integer exactly (no remainder).
