## What are the multiples of 202?

Multiples of 202 are all integers divisible by 202 , i.e. the remainder of the full division by 202 is zero. There are infinite multiples of 202. The smallest multiples of 202 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 202 since 0 × 202 = 0

202 : in fact, 202 is a multiple of itself, since 202 is divisible by 202 (it was 202 / 202 = 1, so the rest of this division is zero)

404: in fact, 404 = 202 × 2

606: in fact, 606 = 202 × 3

808: in fact, 808 = 202 × 4

1010: in fact, 1010 = 202 × 5

etc.

## Is 202 a prime number?

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

for 202, the answer is: No, 202 is not a prime number.

## 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 202). 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 14.213 ). 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.
