Introduction to divisibility rule:
In mathematics, a prime number (or a prime) is a natural number that has exactly two distinct natural number divisors: 1 and itself. The first twenty-five prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
Infinitude of prime numbers exists, as demonstrated by Euclid around 300 BC, although the density of prime numbers within natural numbers with 0.
In the mathematics, divisibility has many rules. This divisibility rules are discussed by the following methods. These divisibility rules are very useful to understand the divisibility of the number, which is even number, odd number, and decimal number etc., Here we discuss the rules of dividing the numbers 2 to 10.
One number is divided by another number is known as the divisibility. In the given number the last three number is divisible by 8 is divisibility rules for 8 . For example 345960, in this number divide by 8. The last three number 960 divide by the 8. The number is divided by the fixed number divisor with performing the division operation.
General Divisibility Rule:
Divisibility by 2: This specific types of rule, given number is divided by two is the divisibility by 2.
Divisibility by 3: This specific types of rule is the summation of the given number divide 3 is divisibility by 3. For example 333 {3+3+3=9} so the number 9 is divide by the 3. The given number is the divisibility by 3.
Divisibility by 4: Given number the last three numbers is divided by the 4 is the divisibility by 4. For instance 24320, last two numbers (20) is the divide by 4.
The rule for divisibility 5: If the taken number the last digit is divides by 5 is the divisibility of the 5 rule.
The rule for divisibility 6: Taken number is divisibility du the number 3 and number 2 is the divisibility for 6.
The rule for divisibility for 7: If in the taken number the last digit, double it, and from the number subtract it. If the answer can be divided by the number 7 then it is divisibile by 7.
The rule for divisibility for 10: The number with 0 at its units/ones place is divisible by 10.
The rule for divisibility for 12: The divisibility includes number of rules. Given number is divisibile by the number 4 and 3 then it is the divisibile for number 12. The summation of the given number is divisibility by 3 and the last two numbers is divisibility by 4 then that number is divisibile of rule 12.
Divisibility Rule for 8:
Given the number 567960, if the last three numbers is divide by 8 is the divisibility of 8.the given number the last three numbers is divide by the 8. The last three number not divide by 8 is not divisibility 8
Ex 1: Find out the following number is the divisibility by 8 or not 74824.
Sol:
Step 1: The given number is the 74824.
Step 2: Check if the given number the last three number divide by 8.
Step 3: The last 3 number is 824. This number is divide by 8.
Step 4: Given number 74824 is divisibility by the 8.
Ex 2: Find out the following number is the divisibility by 8 or not 158825.
Sol:
Step 1: The given number is the 158825.
Step 2: Check if the given number the last three number divide by 8.
Step 3: The last 3 number is 825. This number is not divide by 8.
Step 4: Given number 158825 is not divisibility by the 8.
