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.

What is a factor of the sum of the digits equals 3 or a multiple of 3?
A factor of a number is an integer that divides the number without leaving a remainder. When the sum of the digits of a number equals 3 or a multiple of 3, it indicates that the number itself is divisible by 3. This is because the divisibility rule for 3 states that if the sum of the digits of a number is divisible by 3, then the number itself is also divisible by 3. Therefore, any factor of a number where the sum of its digits equals 3 or a multiple of 3 will also be a factor of the number itself.
