It is called a factor
No. A factor is a number which divides exactly into another number. So the factors of 150 are: 1,2,3,5,10,15,25,50,75.
A factor is a number by which another is exactly divisible. Every number has factors. Some numbers have the same factors as other numbers. Those are common factors. When comparing lists of common factors, the largest number is called the greatest common factor, or GCF.
Do you mean what is a number that has exactly two factors? If so the answer is a prime number. Eg. 2,3,5,7,11..... They are only divisible by 1 and themselves
In Mathematics, a factor is a number or algebraic expression by which another is exactly divisible.
A factor is a number or algebraic expression by which another is exactly divisible.
A factor of a integer is an integer that divides the second integer into a third integer exactly; i.e. A is a factor of B if B/A is exactly C, where all of A, B and C are integers. A prime factor is a factor as above, but is also a prime number. This means that the only factors of that factor are one and the number itself; i.e. A is a prime factor of B if B/A is exactly C andthe only factors of A are 1 and A.
A number that has exactly two (positive) factors is called a prime number. For instance, the only factors of 7 are 1 and 7.
There are exactly two whole number factors of any prime number. The first factor is '1'. The other factor is the prime number itself.
