713is an odd number,as it is not divisible by 2
The factors for 713 are all the numbers between -713 and 713 , which divide 713 without leaving any remainder. Since 713 divided by -713 is an integer, -713 is a factor of 713 .
Since 713 divided by -713 is a whole number, -713 is a factor of 713
Since 713 divided by -31 is a whole number, -31 is a factor of 713
Since 713 divided by -23 is a whole number, -23 is a factor of 713
Since 713 divided by -1 is a whole number, -1 is a factor of 713
Since 713 divided by 1 is a whole number, 1 is a factor of 713
Since 713 divided by 23 is a whole number, 23 is a factor of 713
Since 713 divided by 31 is a whole number, 31 is a factor of 713
Multiples of 713 are all integers divisible by 713 , i.e. the remainder of the full division by 713 is zero. There are infinite multiples of 713. The smallest multiples of 713 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 713 since 0 × 713 = 0
713 : in fact, 713 is a multiple of itself, since 713 is divisible by 713 (it was 713 / 713 = 1, so the rest of this division is zero)
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 713, the answer is: No, 713 is not a prime number.
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 713). 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 26.702 ). 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.
