In addition we can say of the number 44 that it is even
44 is an even number, as it is divisible by 2 : 44/2 = 22
The factors for 44 are all the numbers between -44 and 44 , which divide 44 without leaving any remainder. Since 44 divided by -44 is an integer, -44 is a factor of 44 .
Since 44 divided by -44 is a whole number, -44 is a factor of 44
Since 44 divided by -22 is a whole number, -22 is a factor of 44
Since 44 divided by -11 is a whole number, -11 is a factor of 44
Since 44 divided by -4 is a whole number, -4 is a factor of 44
Since 44 divided by -2 is a whole number, -2 is a factor of 44
Since 44 divided by -1 is a whole number, -1 is a factor of 44
Since 44 divided by 1 is a whole number, 1 is a factor of 44
Since 44 divided by 2 is a whole number, 2 is a factor of 44
Since 44 divided by 4 is a whole number, 4 is a factor of 44
Since 44 divided by 11 is a whole number, 11 is a factor of 44

Multiples of 44 are all integers divisible by 44 , i.e. the remainder of the full division by 44 is zero. There are infinite multiples of 44. The smallest multiples of 44 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 44 since 0 × 44 = 0
44 : in fact, 44 is a multiple of itself, since 44 is divisible by 44 (it was 44 / 44 = 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 44, the answer is: No, 44 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 44). 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 6.633 ). 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.
