Introduction to learn divisor:
In learning divisor many students undergo difficulties in it. They find difficulty in multi-digit divisor. To overcome that we should be careful in selecting the numerals, so it may help the students a lot with the divisor learning–and also from the arithmetic operations used from the divisor. They have to group the numbers when they multiply the numerals with the quotient of the divisor. Please express your views of this topic What is a Divisor by commenting on blog.
Definition of Integers in learn divisor:
The divisor is the digit that the dividend is divided by (in long division). The dividend divided through divisor is known as the quotient (plus a remainder).
One of two or more integers that can be exactly divided into another integer, the number by which a dividend is divided. What does n|m mean? It explains n divides m. For an example 5|10, or 5 divides 10. Do you know when n divides m or when n is a correct divisor of m? I think you do. Understanding List of Composite Numbers is always challenging for me but thanks to all math help websites to help me out.
Let’s see an example on learn divisor:
1)10 divides 20 or 10|20, we know..
The value twenty is divided by ten is written as two x two x five.
The value ten can be written as two x five
20 = 2 X 2 X 5 = 2^2 X 5 and
10 = 2 X 5
2) But 15 does not divides 20,
The value twenty cannot be divide by 15
20 = 2^2 X 5 and
15 = 3 X 5
3) Then why does 10 divide 20 but not 15 ?
We already know, 20 = 2^2 X 5
15 does not divide 20 for the reason that, 15 contains a prime factor ( 3) which is not exist in 20.
Likewise, 14 does not divides 20 as it contains a prime factor (7) which is not exist in 20.
Note that, 14 = 2 X 7
4) Again, 8 does not divides 20. Why?
20 = 2^2 X 5
8 = 2^3
Do you get it? 8 do not include any prime factors which do not exist in 20, then why does 8 not divide 20?
Answer is very easy; just have a close look at the power of 2.
