1201is an odd number,as it is not divisible by 2
The factors for 1201 are all the numbers between -1201 and 1201 , which divide 1201 without leaving any remainder. Since 1201 divided by -1201 is an integer, -1201 is a factor of 1201 .
Since 1201 divided by -1201 is a whole number, -1201 is a factor of 1201
Since 1201 divided by -1 is a whole number, -1 is a factor of 1201
Multiples of 1201 are all integers divisible by 1201 , i.e. the remainder of the full division by 1201 is zero. There are infinite multiples of 1201. The smallest multiples of 1201 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 1201, the answer is: yes, 1201 is a prime number because it only has two different divisors: 1 and itself (1201).
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 1201). 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 34.655 ). 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.
