What number has exactly 8 factors?

24=2*2*2*3 has 8 factors: 1, 2, 3, 4, 6, 8, 12, 24. 24 is the smallest number with 8 factors, as simple verification for numbers below 24 show 24 is first one with this property.

How many numbers has 8 factors?

Table of Factors and Multiples

Which number has the smallest number of divisors?

The number of divisors of 120 is 16. In fact 120 is the smallest number having 16 divisors. Find the smallest number with 2**500500 divisors.

How many divisors does 1 have?

1 is a special case for almost everything. In this case, because it is the only natural number with no proper divisors, just as your definition implies. General rule with number theory: 1 is always weird.

How many divisors a number has?

In general, if you have the prime factorization of the number n, then to calculate how many divisors it has, you take all the exponents in the factorization, add 1 to each, and then multiply these “exponents + 1″s together.

How many divisors does 4 have?

Example: 4 has for divisors 2 and 1. And 2+1=3 inferior to 4, so 4 is a deficient number.

What is a number with 8 zeros called?

One hundred million
One hundred million has eight zeros (100,000,000). When you make the jump from one large number to the next designation (for instance, from one million to one billion), you’ll add a group of three zeros.

Does 1 have any divisors?

Every integer (and its negation) is a divisor of itself. Integers divisible by 2 are called even, and integers not divisible by 2 are called odd. A non-zero integer with at least one non-trivial divisor is known as a composite number, while the units −1 and 1 and prime numbers have no non-trivial divisors.
