The number 1 is the only common factor of co-prime numbers, which is what makes them co-prime. 9 and 10 for example or 15 and 23.
The greatest common factors (GCF) of two numbers is one of the numbers when the larger number is a multiple of the smaller number. Examples: The GCF of 10 and 20 is 10 (2 x 10 = 20) The GCF of 29 and 87 is 29 (3 x 29 = 87)
The prime factors of 4 are 2 and 2. The prime factors of 9 are 3 and 3. They do not have any prime factors in common, so they are relatively prime.
370 10, 37 2, 5, 37 Note: 37 is a prime number
All numbers have factors. Some factors are prime numbers. These are known as prime factors. Some numbers have some of the same prime factors as other numbers. These are known as common prime factors. 3 is a common prime factor of 12 and 15.
No. 10 is not a prime number, which means it cannot be a prime factor. It can be a factor, but not a prime factor.
Five is prime and a factor of both numbers.
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.
20 - 10 and 2 (2 is prime) from 10 do 5 and 2 (both prime)
It is 17.
2 and 7 are prime numbers less than 10 that are factors of 42 and 70.
The prime factor of 7 is 7. The prime factor of 8 is 2. The prime factor of 9 is 3. The prime factors of 10 are 2 and 5. The prime factor of 11 is 11.
Out of 10, 14, 16 and 24, 16 has one prime factor that repeats.
10=2*5 Any number that doesn't have a factor of 2 or 5 is relatively prime to 10. e.g. 3, 7, 11, and 21 are all relatively prime to 10. 2, 5, 15, 16, and 20 are not relatively prime since they share a factor or 2 or 5 (or both, which means they share a factor of 10, e.g. 20).
The number 1 is the only common factor of co-prime numbers, which is what makes them co-prime. 9 and 10 for example or 15 and 23.

3 is a prime number. 4 and 10 are both composite numbers having 2 as a factor.
