Prime factorization of 995

Divide by the smallest prime that fits, and keep going until the quotient is 1:

The primes you divided by give 995 = 5 × 199. From the exponents you can also count the factors without listing them: (1 + 1) × (1 + 1) = 4.

Properties of 995

• 995 is a composite number.
• The sum of all its factors is 1,200; the sum of its proper factors (excluding 995) is 205, which makes it a deficient number (its proper factors add up to less than itself).
• 995 is not a perfect square, so its factors pair up evenly.
• Multiples of 995 include 1,990, 2,985, 3,980, 4,975 and so on.
