Number of factor pairs = number of rectangles
As I understand it, the number of factor pairs is equal to the number of rectangles.
A factor is what goes into a number, a multiple is what a number goes into. 3 is a factor of 9 27 is a multiple of 9.
The key factor in describing population is the number of people and how they spread out across the landscape.
No. A number cannot be both a factor and a multiple of another number. A number can be multiple and factor of itself, but nothing else.
They have a converse relationship. A factor is a number that divides into another, with no remainders. A multiple is something that can be multiplied by another number, to reach the original number that you had. Thus: Original number / a factor = a multiple Multiple * (the correct factor) = original number. "the correct factor", because most number have more than one factor. But only one factor * multiple will give the original number.
One rectangle for each factor pair.
There is no multiple of 10 that's a factor of 45.
Which number is a factor of 10 , but not a multiple of 5
A factor is a number or algebraic expression by which another is exactly divisible. A multiple is a number that can be divided by another number without a remainder. A multiple factor is an oxymoron.
The number is 18, It is even number, it is factor of 198 and multiple of 9
If 21 is a multiple of the number, the number cannot have 90 as a factor.
