# What is the definition of prime composite?

A prime number is a natural number that has exactly two distinct natural number divisors: 1 and itself.

A composite number is a positive integer which has a positive divisor other than one or itself.

# Is 9 a prime or composite number?

A prime number is not divisible by any numbers except 1 and itself. A composite number is divisible by other numbers. 9 is divisible by 3, so it is a composite number.

# What are all the prime numbers from 1-100?

A prime number is a number that is divisible by 2 positive integers - itself and one.

The prime numbers from 1-100 are:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

1 is not a prime number because 1 is divisible by one positive integer, 1.

0 is not a prime number because it is divisible by an infinite number of positive integers.

Also 1 and 0 are neither prime nor composite.

# Is 1025 composite number?

From the fact that it ends in a 5 you should know that it is divisible by 5. So it is composite.

The full factorisation is: 1025 = 52 * 41

# Is 2311 a prime or composite number?

The number 2311 is a prime number having no factors other than 1 and itself.

# You are a composite number between 41 and 50 the sum of your prime factor is 14 What number are you?

Very simple. The answer is 49, because it is between 41-50 and 7+7=14, and 7 multiplied by 7=49.

Example:

22 = 4,

3*5 = 15

and 7*11 = 77

# Is 23 composite or prime?

The number 23 is a prime number. It has only 1 and 23 as its factors.

# What is average of the first 5 composite numbers?

The first 5 composite numbers are 4, 6, 8, 9, and 10. 4 + 6 + 8 + 9 + 10 = 37, so their average is 37/5, or 7.4.

# When beginning a factor tree of a composite number does it matter which factor pair you start with?

no because there are multiple ways to do factor trees until u get to all prime numbers

# What is a prime factor of the composite number 36?

Divide by 2, 3, 5, 7 etc

2x2x3x3=36

# What are the composite numbers between 70 and 90?

The composite numbers are: 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86 ,87, 88

# Is 41 composite or prime?

The number 41 is a prime number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

To test a number to find out if it is prime or composite, try dividing it by the first few prime numbers:

• 41 ÷ 2 = 20 r 1
• 41 ÷ 3 = 13 r 2
• 41 ÷ 5 = 8 r 1
• 41 ÷ 7 = 5 r 6
We don't have to test 4 or 6, since they are both divisible by 2. The divisor (7) is now larger than the result (5 remainder 6), so we can stop. 41 is prime.

# What are the first 10 composite numbers?

The first 10 composites are: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18.

# Are all numbers that have a 2 in the ones place composite numbers?

Yes, all numbers that have 2 in the one's place are composite numbers. In fact, all even numbers except for 2 itself are composite numbers.

# Is 648 a prime number or a composite number?

648 is not prime. 648 = 2 * 2 * 2 * 3 * 3 * 3 * 3
