In addition we can say of the number 94 that it is even
94 is an even number, as it is divisible by 2 : 94/2 = 47
The factors for 94 are all the numbers between -94 and 94 , which divide 94 without leaving any remainder. Since 94 divided by -94 is an integer, -94 is a factor of 94 .
Since 94 divided by -94 is a whole number, -94 is a factor of 94
Since 94 divided by -47 is a whole number, -47 is a factor of 94
Since 94 divided by -2 is a whole number, -2 is a factor of 94
Since 94 divided by -1 is a whole number, -1 is a factor of 94
Since 94 divided by 1 is a whole number, 1 is a factor of 94
Since 94 divided by 2 is a whole number, 2 is a factor of 94
Since 94 divided by 47 is a whole number, 47 is a factor of 94
Multiples of 94 are all integers divisible by 94 , i.e. the remainder of the full division by 94 is zero. There are infinite multiples of 94. The smallest multiples of 94 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 94 since 0 × 94 = 0
94 : in fact, 94 is a multiple of itself, since 94 is divisible by 94 (it was 94 / 94 = 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 94, the answer is: No, 94 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 94). 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 9.695 ). 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.
