## What are the multiples of 70?

Multiples of 70 are all integers divisible by 70 , i.e. the remainder of the full division by 70 is zero. There are infinite multiples of 70. The smallest multiples of 70 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 70 since 0 × 70 = 0

70 : in fact, 70 is a multiple of itself, since 70 is divisible by 70 (it was 70 / 70 = 1, so the rest of this division is zero)

140: in fact, 140 = 70 × 2

210: in fact, 210 = 70 × 3

280: in fact, 280 = 70 × 4

350: in fact, 350 = 70 × 5

etc.

## Is 70 a prime number?

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

for 70, the answer is: No, 70 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 70). 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 8.367 ). 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.
