Accordingly:

101 is multiplo of 1

101 has 1 positive divisors

## Parity of 101

101is an odd number,as it is not divisible by 2

## The factors for 101

The factors for 101 are all the numbers between -101 and 101 , which divide 101 without leaving any remainder. Since 101 divided by -101 is an integer, -101 is a factor of 101 .

Since 101 divided by -101 is a whole number, -101 is a factor of 101

Since 101 divided by -1 is a whole number, -1 is a factor of 101

Since 101 divided by 1 is a whole number, 1 is a factor of 101

## What are the multiples of 101?

Multiples of 101 are all integers divisible by 101 , i.e. the remainder of the full division by 101 is zero. There are infinite multiples of 101. The smallest multiples of 101 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 101 since 0 × 101 = 0

101 : in fact, 101 is a multiple of itself, since 101 is divisible by 101 (it was 101 / 101 = 1, so the rest of this division is zero)

202: in fact, 202 = 101 × 2

303: in fact, 303 = 101 × 3

404: in fact, 404 = 101 × 4

505: in fact, 505 = 101 × 5

etc.

## Is 101 a prime number?

It is possible to determine using mathematical techniques whether an integer is prime or not.

for 101, the answer is: yes, 101 is a prime number because it only has two different divisors: 1 and itself (101).

## How do you determine if a number is prime?

To know the primality of an integer, we can use several algorithms. The most naive is to try all divisors below the number you want to know if it is prime (in our case 101). We can already eliminate even numbers bigger than 2 (then 4 , 6 , 8 ...). Besides, we can stop at the square root of the number in question (here 10.05 ). Historically, the Eratosthenes screen (which dates back to Antiquity) uses this technique relatively effectively.

More modern techniques include the Atkin screen, probabilistic tests, or the cyclotomic test.
