2 and 5
The only factor common to all those numbers is 1.
If the numbers are prime numbers, the prime factor of each number is the number itself. If the numbers are not prime numbers, the prime factors of each number are each of the prime numbers by which the number in question can be divided without a remainder.
The GCF of 10 and 100 is 10.To find the GCF of 10 and 100 you first need to split them into their prime factors:10 = 2x5100 = 2x2x5x5The next step is to identify any common prime factors. In this case, both numbers have a 2 and a 5 as prime factors. To find the GCF, you multiply these numbers together:2x5 = 10Thus the GCF of 10 and 100 is 10.The GCF is 10.
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 numbers (factors) of 100 are: 2 and 5
The prime factors of 100 are: 2, 5
The prime factors of 100 are: 2,5
There are 25 prime numbers from 1 through 100.
1,2,4,5,10,20,25,50,100 2 and 5 are prime.
There are 25 prime numbers between 1 and 100, all of them can be factors.
Each of the 25 prime numbers from 1 to 100 has exactly two factors, 1 and the number itself. The other 75 numbers from 1 to 100 are not prime numbers because none of them have exactly two factors.
2 and 5 are the prime factors of 100.
2 and 5
Numbers with more than two factors are not prime numbers
There are 25 prime numbers and 75 composite numbers from 1 to a 100. A prime number has only two factors whereas a composite number has more than two factors.
By definition, a prime number has exactly two factors. So, there are no prime numbers with exactly three factors.
