There are no three composite numbers whose product is 100. There is a huge number of composite numbers whose sum is 100 - far more than I am prepared to list. 20 + 30 + 50 is one example.

the two prime numbers will be factors of that number, which would make that number a composite number

To find a composite number, think of two numbers that can be multiplied to equal that number. For example, 15 is a composite number because its factors are 1, 3, 5 and 15. For a number to be composite, it should have more than two factors.To know 15 is a composite number, know:1 x 15=153 x 5 =15All composite numbers have more than two factors whereas prime numbers have only two factors.

The product of the GCF and LCM of two numbers is equal to the product of the two numbers. The other number is 126.

Not all numbers are either prime or composite. The number 1/2 is neither prime nor composite. If you are referring only to the natural or counting numbers, note that every natural number is equal to the product of itself and 1 so each number has at least one divisor, itself. If it has no more divisors, then it is prime. If it has more than itself as a divisor, then it is composite.

Product of a prime number and a composite number results in a composite number.Now consider the product of a composite number(a) and a prime number(b) is equal to c.i.e. c = a x bIt is clear that c is divisible by both a and b.Also c is divisible by itself and 1, this means that c has more than two factors.A number having more than two factors is composite, therefore product of a prime number and a composite number results in a composite number.

Assuming you are referring to the prime factors of the number, the product of the prime factors of any composite number is equal to the number itself.

Yes, it is always. Assume temporarily that the product of two prime numbers is not always composite. This implies that that at least one product of prime numbers is also prime. Now, say two different prime numbers p and q, when multiplied, equal r. If r is a prime number, then r's only positive factors are 1 and r. But 1 is not a prime number. This contradicts that both p and q are prime (because either p or q MUST be 1). Therefore, the product of two prime numbers is always composite.

No - although all positive even numbers other than 2 are composite, this does not mean that all composite numbers are even - the first odd composite number is 9, which is equal to 3 x 3.

The product of the GCF and LCM of a pair of numbers is equal to the product of the numbers.

If the signs of both numbers are the same, the product will be positive. If the signs of the numbers are different, the product will be negative.

The product of all whole numbers except zero that are less than or equal to a numbr is a factorial number.
