14 = 2 * 7 42 = 2 * 3 * 7 GCF(14, 42) = 2 * 7 = 14
The greatest common factor of two or more prime numbers is 1.
25 is the greatest common factor. 5 is the greatest prime factor.
If the greatest common factor is 1, then the numbers are said to be co-prime or relatively prime.
73 is a prime number so 51,3x17 and 73 only have the number 1 as the greatest common factor.
As the numbers are all prime, the only factors each of them has are 1 and the number itself. Therefore the greatest, and only, common factor of two of more prime numbers is 1.
2 is the greatest common factor and it is prime
Yes. The greatest common factor of 4 and 10 is 2, which is a prime number. The greatest common factor of 51 and 81 is 3, which is a prime number.
You do a factor rainbow to find a prime factorization. You compare prime factorizations to find a greatest common factor.
The greatest prime factor of 40 is 5. The greatest prime factor of 63 is 7. They do not have any prime factors in common.
Use a factor tree. 172 86, 2 43,2,2
The greatest common factor of 54 and 99 is 9, which is not prime. The greatest common factor of 80 and 114 is 2, which is prime.
The greatest common prime factor of 10 and 20 is 5.
The greatest common factor of two or more prime numbers is 1.
The greatest prime factor they have in common is 2.
The greatest common factor of 77 and 88 is 11, and it is also the greatest prime factor.
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 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 factors of 45 are 3, 3, and 5. The prime factors of 60 are 2, 2, 3, and 5. The common prime factors are 3 and 5, so the greatest common factor is 3 x 5 = 15.
