Is 47819 a prime number? What are the divisors of 47819?

Is 47819 a prime number?

Yes, 47819 is a prime number.

Indeed, the definition of a prime numbers is to have only 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 47819, the only two divisors are 1 and 47819. Therefore 47819 is a prime number.

As a consequence, 47819 is only a multiple of 1 and 47819.

Since 47819 is a prime number, 47819 is also a deficient number, that is to say 47819 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 47819 without 47819 itself (that is 1, by definition!).
