## Which 3 digit number has the greatest number of different factors?

Let N be the three-digit number which has the greatest number of different factors. Since 2×3×5×7×11>1000, N at most has four different prime factors. If N only has one prime factor, then N=29, and so N has 10 different factors.

## Which number has the most number of factors?

You might check out OEIS on highly composite numbers. 840 has 32 factors, while 960 has only 28, but maybe the 7 isn’t so useful. The next record holder is 1260 with 36 factors.

### How many numbers from 1 to 100 are there?

There are 98 whole numbers between 1 and 100.

### How many 2 digit numbers are there?

The total number of two digit numbers is 90. From 1 to 99 there are 99 numbers, out of which there are 9 one-digit numbers, i.e., 1, 2, 3, 4, 5, 6, 7, 8 and 9. If one digit numbers are subtracted from 99 we get 90 two-digit numbers.

**What 4 digit number has the most factors?**

9999

Write the Greatest 4 Digit Number And Express It in Terms Of Its Prime Factors. The largest 4-digit number is 9999.

#### What is a greatest number?

The greatest number is formed by placing the given digits in descending order. This is because the digit’s position at the extreme left of a number increases its place value. So the greatest digit should be placed at the extreme left side of the number to enhance its value.

#### What is the smallest 3 digit number with unique digits?

## How many three digit numbers have exactly three factors?

Squares of these numbers are three digit numbe If N = a^p * b^q * c^r *…. , where a, b, and c are prime factors and p, q, and r are integers, then the number of factors of N = (p+1) (q+1) (r+1)……. In this problem, we have to find the three digit numbers, which have exactly three factors. 3 can be written only as (2+1), which implies ‘p’ is 2.

## Which is the number with the most factors?
