It is possible to find out using mathematical methods whether a given integer is a prime number or not.
Yes, 10 753 is a prime number.
Indeed, the definition of a prime numbers is to have exactly two distinct positive divisors, 1 and itself. A number is a divisor of another number when the remainder of Euclid’s division of the second one by the first one is zero. Concerning the number 10 753, the only two divisors are 1 and 10 753. Therefore 10 753 is a prime number.
