In addition we can say of the number 746 that it is even
746 is an even number, as it is divisible by 2 : 746/2 = 373
The factors for 746 are all the numbers between -746 and 746 , which divide 746 without leaving any remainder. Since 746 divided by -746 is an integer, -746 is a factor of 746 .
Since 746 divided by -746 is a whole number, -746 is a factor of 746
Since 746 divided by -373 is a whole number, -373 is a factor of 746
Since 746 divided by -2 is a whole number, -2 is a factor of 746
Since 746 divided by -1 is a whole number, -1 is a factor of 746
Multiples of 746 are all integers divisible by 746 , i.e. the remainder of the full division by 746 is zero. There are infinite multiples of 746. The smallest multiples of 746 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 746, the answer is: No, 746 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 746). 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 27.313 ). 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.
