Suppose you are asked to find remainder of following expression Person with average math skills will do all the calculation and come with the answer.But the Question can be easily solved using Remainder Theorem REMAINDER THEOREM In this process, you have to individually calculate each values and write the remainders This way you can easily …
CONCEPT 1 Suppose you are given a number in factorial numbers and you are asked to find number of zeros possible in that factorial. In questions involving number of zeros, you have to find the possible combination of (2 * 5) For example:Find number of zeros in 6! 6! can be written as 6 ! …
The number of zero’s in any expression depends on number of combination of (2 *5) present in that expression.Hence zeros are formed by the combination of 2 & 5 For Example; Suppose you are asked to find number of zeros in following expression8 * 15 * 23 * 17 * 25 * 22 Step 1: …
Question 01 Find number of zeros in following expressions12 * 15 * 5 * 24 * 13 * 17 The Question can be easily solved if you can find the number of (2 * 5) combination in the expression Step 1Reformulating the expression into simpler form Step 2Number of 2 in above expression = 5Number …
Let us suppose you have given number 240 to find the number of factors Factor representation of 240 is Using conventional method, you can find number of factors by manual calculation So using this old method we can figure out that there are total 20 factors of number 240.But this method is tedious and consumes …
Sum of Factors CalculationLet us suppose that you are asked to find the sum of all the factors of a number. Let the number be 240Factor representation of 240 will be like From the above representation, we can write total factors as You can see from the above calculations, there are 20 numbers which divide …
What are Factors of a number?Factors of any numbers are basically the digits which will fully divide that particular numberFor Example: 1. Factor of 6 are: 6=> 2*3 Here 2 and 3 are the digits which will fully divide number 6 Hence, 2 & 3 are factor of number 6 2. Calculate Individual factors of …
