Is 469 a prime number?

It is possible to find out using mathematical methods whether a given integer is a prime number or not.

For 469, the answer is: No, 469 is not a prime number.

The list of all positive divisors (i.e., the list of all integers that divide 469) is as follows: 1, 7, 67, 469.

For 469 to be a prime number, it would have been required that 469 has only two divisors, i.e., itself and 1.

As a consequence:

469 is a multiple of 1
469 is a multiple of 7
469 is a multiple of 67

For 469 to be a prime number, it would have been required that 469 has only two divisors, i.e., itself and 1.

However, 469 is a semiprime (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 469 = 7 x 67, where 7 and 67 are both prime numbers.

Is 469 a deficient number?

Yes, 469 is a deficient number, that is to say 469 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 469 without 469 itself (that is 1 + 7 + 67 = 75).

Parity of 469

469 is an odd number, because it is not evenly divisible by 2.

Is 469 a perfect square number?

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 469 is about 21.656.

Thus, the square root of 469 is not an integer, and therefore 469 is not a square number.

What is the square number of 469?

The square of a number (here 469) is the result of the product of this number (469) by itself (i.e., 469 × 469); the square of 469 is sometimes called "raising 469 to the power 2", or "469 squared".

The square of 469 is 219 961 because 469 × 469 = 469² = 219 961.

As a consequence, 469 is the square root of 219 961.

Number of digits of 469

469 is a number with 3 digits.

What are the multiples of 469?

The multiples of 469 are all integers evenly divisible by 469, that is all numbers such that the remainder of the division by 469 is zero. There are infinitely many multiples of 469. The smallest multiples of 469 are:

0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 469 too, since 0 × 469 = 0
469: indeed, 469 is a multiple of itself, since 469 is evenly divisible by 469 (we have 469 / 469 = 1, so the remainder of this division is indeed zero)
938: indeed, 938 = 469 × 2
1 407: indeed, 1 407 = 469 × 3
1 876: indeed, 1 876 = 469 × 4
2 345: indeed, 2 345 = 469 × 5
etc.

How to determine whether an integer is a prime number?

To determine the primality of a number, several algorithms can be used. The most naive technique is to test all divisors strictly smaller to the number of which we want to determine the primality (here 469). First, we can eliminate all even numbers greater than 2 (and hence 4, 6, 8…). Then, we can stop this check when we reach the square root of the number of which we want to determine the primality (here the square root is about 21.656). Historically, the sieve of Eratosthenes (dating from the Greek mathematics) implements this technique in a relatively efficient manner.

More modern techniques include the sieve of Atkin, probabilistic algorithms, and the cyclotomic AKS test.
