The least common factor of any set of positive integers is 1, and 1 does not have a prime factorization.
That's the prime factorization.
Since 72 is a factor of 144, its entire prime factorization will be contained in the prime factorization of 144.
Since 72 is a factor of 144, its whole prime factorization will be contained in the prime factorization of 144.
The prime factorization of 2456 is 2 x 2 x 2 x 307. There is not a greatest common factor. To have a greatest common factor, you need two or more numbers. A common factor is a factor that two or more number have in common. However, the prime factorization of all the numbers will help you find the greatest common factor. The greatest common factor will be the prime factors they have in common multiplied together. Examples: The prime factorization of 36 is 2 x 2 x 3 x 3. The prime factors it has in common with 2456 are 2 and 2, so the greatest common factor is 2 x 2 = 4. The prime factorization of 921 is 3 x 307. The prime factors that it has in common with 2456 is 307, so the greatest common factor is 307.
You do a factor rainbow to find a prime factorization. You compare prime factorizations to find a greatest common factor.
The common prime factor of 171 and 18 is 3.
You do not. To have a greatest common factor, you need two or more numbers. A common factor is a factor that two or more number have in common. However, the prime factorization of all the numbers will help you find the greatest common factor. The greatest common factor will be the prime factors they have in common multiplied together. Example: The prime factorization of 30135 is 3 x 5 x 7 x 7 x 41. The prime factorization of 98 is 2 x 7 x 7. The prime factors they have in common are 7 and 7, so the greatest common factor is 7 x 7 = 49.
The greatest prime factor they have in common is 2.
