Is 5557 a prime number? What are the divisors of 5557?

## Is 5557 a prime number?

Yes, 5557 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 5557, the only two divisors are 1 and 5557. Therefore 5557 is a prime number.

As a consequence, 5557 is only a multiple of 1 and 5557.

Since 5557 is a prime number, 5557 is also a deficient number, that is to say 5557 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 5557 without 5557 itself (that is 1, by definition!).

## Parity of 5557

5557 is an odd number, because it is not evenly divisible by 2.

## Is 5557 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 5557 is about 74.545.

Thus, the square root of 5557 is not an integer, and therefore 5557 is not a square number.

Anyway, 5557 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 5557?

The square of a number (here 5557) is the result of the product of this number (5557) by itself (i.e., 5557 × 5557); the square of 5557 is sometimes called "raising 5557 to the power 2", or "5557 squared".

The square of 5557 is 30 880 249 because 5557 × 5557 = 55572 = 30 880 249.

As a consequence, 5557 is the square root of 30 880 249.

## Number of digits of 5557

5557 is a number with 4 digits.

## What are the multiples of 5557?

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 5557 too, since 0 × 5557 = 0
• 5557: indeed, 5557 is a multiple of itself, since 5557 is evenly divisible by 5557 (we have 5557 / 5557 = 1, so the remainder of this division is indeed zero)
• 11 114: indeed, 11 114 = 5557 × 2
• 16 671: indeed, 16 671 = 5557 × 3
• 22 228: indeed, 22 228 = 5557 × 4
• 27 785: indeed, 27 785 = 5557 × 5
• etc.
