The prime factors of 50 are: 2 and 5
1, 2, 4, 5, 10, 20, 25, 50, and 100. 2 and 5 are prime.
The prime factors of 100 are 2, and 5. The composite factors are 100, 50, 25, 20, 10, and 4. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 have a different name.
The factors of 100 are: 1 2 4 5 10 20 25 50 100 The prime factors are: 2 x 2 x 5 x 5
The prime factors of 100 are 2 x 2 x 5 x 5, and one more x 2 gives the prime factors of 200, 2 x 2 x 2 x 5 x 5. The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. These are also the common factors of 100 and 200, but there is no obvious way to find the factors of 200 by using common factors. The factors of 200 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, and 200.
1, 2, 4, 5, 10, 20, 25, 50, 100 2 and 5 are prime.
To find the greatest factor of a number (other than itself) you first need to find the prime factors of that number. In this case, the prime factors of 100 are 2, 2, 5 and 5. The next step is to multiply all these together, except the smallest (2). This means you multiply 2x5x5. That works out at 50. Thus the greatest factor of 100 (other than itself) is 50.

The prime factors of 100 are 2 x 2 x 5 x 5, and one more x 2 gives the prime factors of 200, 2 x 2 x 2 x 5 x 5. The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. These are also the common factors of 100 and 200, but there is no obvious way to find the factors of 200 by using common factors. The factors of 200 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, and 200.
Factors: 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200.Prime Factors: 2, 5
All the factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100, 1,2, and 5 are prime numbers, so the composite number factors of 100 are 4, 10, 20, 25, 50, and 100.
Prime factorization is a way to express every composite number as the product of prime numbers(or prime factors). Let us consider the number 100. Prime factorization of 100 = 2 x 2 x 5 x 5. It can be seen that there are two distinct prime factors: 2 and 5. And 5 is the greatest prime factor. 100 can be expressed as 2 x 50. The only prime factor we have in this expression is 2 and this makes us to think that 2 is the only prime factor of 100, which is untrue. So with the help of prime factorization it is possible to find all the prime factors and the greatest prime factor.
