Math Blogs on Grade VI

Hello friends, in this session we are going to learn about the some of the interesting part of mathematics related to different topics. This article will include that how to find factors and multiples of the number or variable and expressions. We will also go through by greatest common factors (GCF), so just talking about the level of this, the session is for grade VI of gujarat state education board.
First talking about factors that any of the number is made by multiplication of two or more numbers. All the numbers that are multiplied to form that number are called as the factors of that number. So, factors in the mathematical definition are the divisor of any number that evenly divides the number without leaving any remainder. Factor is also a whole number that divides any number into a whole number. In math questions We use the process of factorization for making factors. Factorization is the process of breaking any number in to its factors. All the numbers have a universal factor as one and each of the number can be divided by themselves and produce one so number itself is also a factor and To know more about factors refer this.For example: number 32 can be divided in to 2 and 16, and again 16 can be divided into 24 (2 * 2 * 2 * 2), 24 have factors as 1, 2, 3, 4, 6, 8, 12, and 24. Any of the even numbers has a factor two; any number ending with 5 has a factor 5 also. Any number ending with zero (except zero itself) has always at least two factors as 2 and 5. Multiple of a number is a number that on multiplying with any whole number gives another number. For example 12 has factors 3 and 4, so 12 is a multiple of 3. Another example can be 5, so the multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40, etc. Factors and multiples are the similar words as 12 have factors 3 and 4, and the multiple of 3 and 4 is 12. To find a multiple of a whole number we have to take the product of counting number with that whole number. For example to find the multiples of 7 we have to multiply 7 with 1, 2, 3, 4, 5 and so on thus the multiples are 7, 14, 21, 28, 35, 42, 49, 56, and so on. The list for multiples for any number is endless.
Now talking about greatest common factor, the GCF of a number is the largest numbers that divides evenly into all of the numbers. For example the GCF of some numbers:
12           =             1, 2, 3, 4, 6, 12
16           =             1, 2, 4, 8, 16
24           =             1, 2, 3, 4, 6, 12, 24
So the greatest common factor in these numbers is 4 (underlined number in factors). So a GCF is a number that is also a common factor for all the given numbers. It is just a greatest number in the all common factors.

This is all about the Factors and multiples and if anyone wants to know about How to tackle Decimals and Percentage problems?  and Percentages in Grade VI then they can refer to Internet and text books for understanding it more precisely.
