What are the multiples of 490?
Multiples of 490 are all integers divisible by 490 , i.e. the remainder of the full division by 490 is zero. There are infinite multiples of 490. The smallest multiples of 490 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 490 since 0 × 490 = 0
490 : in fact, 490 is a multiple of itself, since 490 is divisible by 490 (it was 490 / 490 = 1, so the rest of this division is zero)
etc.
Is 490 a prime number?
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 490, the answer is: No, 490 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 490). 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 22.136 ). 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.
