How about: 10
The only number that has only one factor is '1'. Every other number has at least two factors: '1' and itself. If there are no more than that, then the number is a prime number.
Once your prime factorization is complete and you discover that there are no numbers in common, the GCF is one and the numbers are declared to be relatively prime.
Saying "The" Instead of "A"The prime factorization is used instead of a prime factorization because there is only one correct prime factorization of any given number. Of course, that refers to composite numbers because prime numbers have no prime factorization.The use of the word "a" implies that more than one prime factorization is possible when it's not. The use of the word "the" signifies that only one prime factorization is possible, though there are various ways to arrive at it.
You need at least two numbers to find a GCF. The prime factorization of 99 is 3 x 3 x 11. Once you have the other one, you can compare.
Only one - which is repeated.
No, multiplying a set of numbers can only come out as one product. Therefore, two numbers having the same prime factorization is impossible.
Factor strings don't necessarily have to be composed entirely of prime numbers. But the longest factor string, the one that is entirely prime numbers, that's the prime factorization.
All the even numbers and the odd multiples of 5.
10, 20, 30, 40, 50, 60, 70, 80, 90
The prime factorization of 45 is 3 x 3 x 5. To find an LCM it is necessary to compare and combine that prime factorization with at least one other.
10, 20, 30, 40, 50, 60, 70, 80, and 90.
10, 20, 30, 40, 50, 60, 70, 80, 90
