Question

Is 35 a prime number?

Answer 1

Hint: This is a simple question to solve. In order to find whether the given number is prime or not we should know what are prime numbers? And then only we can check for the given number above if it is prime or not. Prime numbers are those numbers that are divisible by 1 and the number itself. Now we will apply this on the number above and check for it.

Complete step by step answer:
Given the number is 35. We have to check if it is prime or not.
For that we will divide the number by natural numbers and if the remainder is 0 then it is divisible.
Or we can directly check for the factors of the given numbers.
Now we can definitely say that 1 and 5 are the factors. Because the unit's place has digit 5.
Next it is divisible by 7 also. Because 7 multiplied by 5 gives 35.
Thus overall 1, 5, 7 and 35 are the factors of 35.
Since we get factors apart from 1 and 35 that divide the number.
Thus 35 is not a prime number.

Note:
Note that, 2 is the first prime number we consider in the series of prime numbers. Exact opposite of prime numbers are composite numbers. But prime numbers have only factors 1 and the number itself. generally students get confused between even-odd numbers and prime-composite numbers. Even-odd concept is simply based on the divisibility test of 2. If the number is divisible by 2 then it is even otherwise it is odd.
Whereas prime and composite is the concept based on a number of factors.
