In addition we can say of the number 146 that it is even
146 is an even number, as it is divisible by 2 : 146/2 = 73
The factors for 146 are all the numbers between -146 and 146 , which divide 146 without leaving any remainder. Since 146 divided by -146 is an integer, -146 is a factor of 146 .
Since 146 divided by -146 is a whole number, -146 is a factor of 146
Since 146 divided by -73 is a whole number, -73 is a factor of 146
Since 146 divided by -2 is a whole number, -2 is a factor of 146
Since 146 divided by -1 is a whole number, -1 is a factor of 146
Multiples of 146 are all integers divisible by 146 , i.e. the remainder of the full division by 146 is zero. There are infinite multiples of 146. The smallest multiples of 146 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 146, the answer is: No, 146 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 146). 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 12.083 ). 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.
