Is 1669 a prime number? What are the divisors of 1669?

## Is 1669 a prime number?

Yes, 1669 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 1669, the only two divisors are 1 and 1669. Therefore 1669 is a prime number.

As a consequence, 1669 is only a multiple of 1 and 1669.

Since 1669 is a prime number, 1669 is also a deficient number, that is to say 1669 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 1669 without 1669 itself (that is 1, by definition!).

## Parity of 1669

1669 is an odd number, because it is not evenly divisible by 2.

## Is 1669 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 1669 is about 40.853.

Thus, the square root of 1669 is not an integer, and therefore 1669 is not a square number.

Anyway, 1669 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 1669?

The square of a number (here 1669) is the result of the product of this number (1669) by itself (i.e., 1669 × 1669); the square of 1669 is sometimes called "raising 1669 to the power 2", or "1669 squared".

The square of 1669 is 2 785 561 because 1669 × 1669 = 16692 = 2 785 561.

As a consequence, 1669 is the square root of 2 785 561.

## Number of digits of 1669

1669 is a number with 4 digits.

## What are the multiples of 1669?

The multiples of 1669 are all integers evenly divisible by 1669, that is all numbers such that the remainder of the division by 1669 is zero. There are infinitely many multiples of 1669. The smallest multiples of 1669 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 1669 too, since 0 × 1669 = 0
• 1669: indeed, 1669 is a multiple of itself, since 1669 is evenly divisible by 1669 (we have 1669 / 1669 = 1, so the remainder of this division is indeed zero)
• 3 338: indeed, 3 338 = 1669 × 2
• 5 007: indeed, 5 007 = 1669 × 3
• 6 676: indeed, 6 676 = 1669 × 4
• 8 345: indeed, 8 345 = 1669 × 5
• etc.
