What are all the prime numbers from 1-75?
The prime numbers from 1 - 75 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, and 73.
All even numbers greater than 2 are composites, so 752 is a composite.
Is 1814 a prime number or composite number?

How can you find the prime factorization of a composite numbers?
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.
Example: 210
210 Divide by two.
105,2 Divide by three.
35,3,2 Divide by five.
7,5,3,2 Stop. All the factors are prime.
2 x 3 x 5 x 7 = 210
That's the prime factorization of 210.
As an even number greater than 2, 1874 is divisible by 2 and therefore composite. Its positive integer factors are:
1, 2, 937, 1874
Is number 1a prime or composite number?
