## Is 9 a perfect square?

In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it can be written as 3 × 3.

## Why is 30 not a square number?

So now we know the digital root of 30 is 3. Is 3 in the list of digital roots that are always a square root (1, 4, 7 or 9)? Answer: NO, 3 is not in the list of digital roots that are always perfect squares. We can conclude that 30 IS NOT a perfect square and we don’t need to factor!

## What is the greatest prime factor of 1000?

The prime factorization of 1000 is 2 × 2 × 2 × 5 × 5 × 5. A prime number is a number that is only divisibly by 1 and…

## What is the smallest number with 7 factors?

6464 is the smallest. It has these 7 factors: 1,2,4,8,16,32, and 64. 12 has 6 factors (1,2,3,4,6 and 12) and 24 has 8 factors (1,2,3,4,6,8,12 and 24) but you have to go all the way to 64 to get exactly 7 factors.

## How many factors does 50 have?

For example, 50 is a multiple of all these numbers: 1, 2, 5, 10, 25, and 50. And 1, 2, 5, 10, 25, and 50 are all factors of 50. 50 is a composite number.

## Is 30 a factor or a multiple of 10?

If a is divisible by b, then b is a factor of a, and a is a multiple of b. Example : 30 = 3 × 10, so 3 and 10 are factors of 30 and 30 is a multiple of 3 and 10. Every factor of a number is an exact divisor of that number.

## What are the factors of 28?

The factors of 28 are the numbers, which on multiplication in pairs results in the original number. These factors are 1,2,4,7,14 and 28. Since, 2 x 14 = 28, therefore (2,14) is a pair factor of number 28.

## How many positive factors does 1000 have?

16 Positive FactorsWhen we counted the Factors of 1000 that we listed above, we found that 1000 has 16 Positive Factors and 16 Negative Factors. Thus, the total number of Factors of 1000 is 32.

## What is the missing factor of 30?

30 = 1 x 30, 2 x 15, 3 x 10, or 5 x 6. Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30. Prime factorization: 30 = 2 x 3 x 5.

## What is the HCF of 1000?

We found the factors and prime factorization of 10 and 1000. The biggest common factor number is the GCF number. So the greatest common factor 10 and 1000 is 10.

## What is the largest prime factor of 30?

30 is a composite number. 30 = 1 x 30, 2 x 15, 3 x 10, or 5 x 6. Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30. Prime factorization: 30 = 2 x 3 x 5.

## What are factors of 30 but not 15?

The factors of 30 are 1, 2, 3, 5, 10, 15, and 30. The common factors of 15 and 30 are 1, 3, 5, and 15.

## What are the factors of 20 and 30?

The numbers 20 and 30 have the factors 2 and 5 in common. Next, multiply the common factors to find the GCF. If there is only one common factor, there is no need to multiply. The GCF of 20 and 30 is 10.

## Which number has the highest number of factors?

This is the only way to increase the exponents without going over 5000, so the highest number of factors you can reach with a number that has five prime factors is 48, reached by the number 4620.
