What are the three factors of 30?

What are the three factors of 30?

Factors of 30: 1, 2, 3, 5, 6, 10, 15 and 30.

What is the largest 3 digit number having exactly three factors?

Now, The greatest 3 digit perfect square number is 961 (square of 31) and smallest is 100(square of 10). so, the square of all prime numbers which is between 10 and 31 is the 3-digit number which has only 3 factors. Now, primes between 10 and 31 are 11,13,17,19,23,29 and 31.

What number less than 30 has 8 factors?

Solution: The even number below 30 having 8 factors will be 24.

What is the smallest number with 3 factors?

What is a factor of a number 30?

The factors of 30 are 1, 2, 3, 5, 6, 10, 15, 30 and its negative factors are -1, -2, -3, -5, -6, -10, -15, -30.

So that is 32 such numbers.

What is the smallest factor of a number?

number 1
The number 1 is the smallest factor of every number. Every number will have a minimum of two factors, 1 and the number itself.

Which number below is a factor of 16?

The factors of 16 are 1, 2, 4, 8, 16, now if we find the prime factorization of 16, the result would be 16 = 2 x 2 x 2 x 2, which can also be written as 16 = 2⁴. Since √16 = 4, which is a whole number, it can also be called as a perfect square.

How many numbers have exactly 3 factors in them?

The numbers that have exactly 3 factors are squares of prime numbers. The factors must be prime, since any non-prime factor would itself have factors, meaning we’d exclude for example 2 x 3 x 4 = 24 since 4 is 2 x 2, so 24 really has 4 factors.

How to find all factors of negative numbers?

Just be sure to follow the rules of multiplying and dividing negative numbers to find all factors of negative numbers. For example, the factors of -6 are (1, -6), (-1, 6), (2, -3), (-2, 3). See the Math Equation Solver Calculator and the section on Rules for Multiplication Operations .

How can you think of factors in terms of Division?

You can also think about factors in terms of division: The factors of a number include all numbers that divide evenly into that number with no remainder. Consider the number 10. Since 10 is evenly divisible by 2 and 5, you can conclude that both 2 and 5 are factors of 10.

How many factors does an integer number have?

It is important to note that every integer number has at least two factors: 1 and the number itself. If a number has only two factors that number is a prime number.
