Is 706 a prime number?

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

For 706, the answer is: No, 706 is not a prime number.

The list of all positive divisors (i.e., the list of all integers that divide 706) is as follows: 1, 2, 353, 706.

For 706 to be a prime number, it would have been required that 706 has only two divisors, i.e., itself and 1.

As a consequence:

706 is a multiple of 1
706 is a multiple of 2
706 is a multiple of 353

For 706 to be a prime number, it would have been required that 706 has only two divisors, i.e., itself and 1.

However, 706 is a semiprime (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 706 = 2 x 353, where 2 and 353 are both prime numbers.

Is 706 a deficient number?

Yes, 706 is a deficient number, that is to say 706 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 706 without 706 itself (that is 1 + 2 + 353 = 356).

Parity of 706

706 is an even number, because it is evenly divisible by 2: 706 / 2 = 353.

Is 706 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 706 is about 26.571.

Thus, the square root of 706 is not an integer, and therefore 706 is not a square number.

What is the square number of 706?

The square of a number (here 706) is the result of the product of this number (706) by itself (i.e., 706 × 706); the square of 706 is sometimes called "raising 706 to the power 2", or "706 squared".

The square of 706 is 498 436 because 706 × 706 = 706² = 498 436.

As a consequence, 706 is the square root of 498 436.

Number of digits of 706

706 is a number with 3 digits.

What are the multiples of 706?

The multiples of 706 are all integers evenly divisible by 706, that is all numbers such that the remainder of the division by 706 is zero. There are infinitely many multiples of 706. The smallest multiples of 706 are:

0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 706 too, since 0 × 706 = 0
706: indeed, 706 is a multiple of itself, since 706 is evenly divisible by 706 (we have 706 / 706 = 1, so the remainder of this division is indeed zero)
1 412: indeed, 1 412 = 706 × 2
2 118: indeed, 2 118 = 706 × 3
2 824: indeed, 2 824 = 706 × 4
3 530: indeed, 3 530 = 706 × 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 706). 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 26.571). 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.
