What are the multiples of 820?

Multiples of 820 are all integers divisible by 820 , i.e. the remainder of the full division by 820 is zero. There are infinite multiples of 820. The smallest multiples of 820 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 820 since 0 × 820 = 0

820 : in fact, 820 is a multiple of itself, since 820 is divisible by 820 (it was 820 / 820 = 1, so the rest of this division is zero)

1640: in fact, 1640 = 820 × 2

2460: in fact, 2460 = 820 × 3

3280: in fact, 3280 = 820 × 4

4100: in fact, 4100 = 820 × 5

etc.

Is 820 a prime number?

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

for 820, the answer is: No, 820 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 820). 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 28.636 ). 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.
