## What is the biggest perfect square that divides into 216?

Let’s write this product of factorials out in its prime factorization: 216 × 37 × 53 × 71. Since we want perfect square factors, we are looking for pairs of primes. The highest perfect square factor is 216 × 36 × 52 = (28 × 33 × 51)2.

## Is 28 a perfect number?

Perfect number, a positive integer that is equal to the sum of its proper divisors. … The smallest perfect number is 6, which is the sum of 1, 2, and 3. Other perfect numbers are 28, 496, and 8,128.

## Is 18 a perfect square?

A: No, the number 18 is not a perfect square.

## What is the prime factorisation of 216?

So, the prime factors of 216 are written as 2 x 2 x 2 x 3 × 3 x 3 or 23 x 33, where 2 and 3 are the prime numbers. It is possible to find the exact number of factors of a number 216 with the help of prime factorisation. The prime factor of the 216 is 23 x 33. The exponents in the prime factorisation are 3 and 3.

## What is the largest perfect square that goes into 18?

9The largest perfect square factor of 18 is 9.

## Why is 28 a special number?

In mathematics It is a composite number, its proper divisors being 1, 2, 4, 7, and 14. Twenty-eight is the second perfect number – it’s the sum of its divisors: 1+2+4+7+14. As a perfect number, it is related to the Mersenne prime 7, since 2(23 − 1) = 28. The next perfect number is 496, the previous being 6.

## What are the common factors of 216 and 54?

The factors of 216 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108 and 216. The factors of 54 are 1, 2, 3, 6, 9, 18, 27 and 54. So, the Greatest Common Factor for these numbers is 54 because it divides all them without a remainder. Read more about Common Factors below.

## IS 216 a perfect?

Answer: 216 is perfect Cube.

## What can go into 144?

Factors of 144: 1, 4, 2, 3, 6, 8, 16, 9, 12, 18, 24, 36, 48, 72, 144.

## Why Is 9 the perfect number?

Nine is a Motzkin number. It is the first composite lucky number, along with the first composite odd number and only single-digit composite odd number. 9 is the only positive perfect power that is one more than another positive perfect power, by Mihăilescu’s Theorem.

## Is 216 and 215 are Coprime numbers?

215 and 216 are co-prime because 1 is the only common factor of these numbers. Factors of 16 are 1, 2, 4, 8 and 16. … Therefore, 1 is the only common factor of 81 and 16 which means that 81 and 16 are co-prime.

## What are the factors of 216?
