Is 1907 a prime number? What are the divisors of 1907?

## Is 1907 a prime number?

Yes, 1907 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 1907, the only two divisors are 1 and 1907. Therefore 1907 is a prime number.

As a consequence, 1907 is only a multiple of 1 and 1907.

Therefore year 1907 was a prime year.

Since 1907 is a prime number, 1907 is also a deficient number, that is to say 1907 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 1907 without 1907 itself (that is 1, by definition!).

## Parity of 1907

1907 is an odd number, because it is not evenly divisible by 2.

## Is 1907 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 1907 is about 43.669.

Thus, the square root of 1907 is not an integer, and therefore 1907 is not a square number.

Anyway, 1907 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 1907?

The square of a number (here 1907) is the result of the product of this number (1907) by itself (i.e., 1907 × 1907); the square of 1907 is sometimes called "raising 1907 to the power 2", or "1907 squared".

The square of 1907 is 3 636 649 because 1907 × 1907 = 19072 = 3 636 649.

As a consequence, 1907 is the square root of 3 636 649.

## Number of digits of 1907

1907 is a number with 4 digits.

## What are the multiples of 1907?

The multiples of 1907 are all integers evenly divisible by 1907, that is all numbers such that the remainder of the division by 1907 is zero. There are infinitely many multiples of 1907. The smallest multiples of 1907 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 1907 too, since 0 × 1907 = 0
• 1907: indeed, 1907 is a multiple of itself, since 1907 is evenly divisible by 1907 (we have 1907 / 1907 = 1, so the remainder of this division is indeed zero)
• 3 814: indeed, 3 814 = 1907 × 2
• 5 721: indeed, 5 721 = 1907 × 3
• 7 628: indeed, 7 628 = 1907 × 4
• 9 535: indeed, 9 535 = 1907 × 5
• etc.
