WHAT ARE THE COMMON PRIME FACTOR IN THIS PAIR OF NUMBERS 21 AND 411?
3
Which pair of numbers has a greatest common factor that is a prime number 54 and 99 or 80 and 114?
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.
Are there any 2 numbers that don't have a common factor?
Since 1, known as the "multiplicative identity", cannot be counted as a factor, there are many pairs of numbers that do not have common factors, such as 2 and 3, 2 and 5, and 3 and 5. There are many pairs of composite (not prime) numbers without common factors, such as 4 and 9. Also, since prime numbers do not have factors, any pair of primes cannot have a common factor, though a pair in which one number is prime may, e.g. 5 and 10.
What pair of numbers is relatively prime 15 and 21 24 and 49 35 and 135 and 45 and 102?
24 and 49 are relatively prime. Their only common factor is 1. All the other pairs have more than the number 1 as a common factor.
Give all the common prime factors each pair of numbers share?
Okay. Give us a pair of numbers.
When is the greatest common factor of a pair of numbers on of the numbers?
A prime number
For which pair is the greatest common factor 1?
Any pair of prime numbers
WHAT ARE THE COMMON PRIME FACTOR IN THIS PAIR OF NUMBERS 21 AND 411?
3
When a pair of numbers have ONLY 1 as the common factor what is it called?
relatively prime or co-prime.
What are the common factors of the pair numbers 13 and 7?
' 1 ' is their only common factor. They're both prime numbers.
Can a pair of numbers have fewer than two common factors?
Yes, a pair of numbers can have fewer than two common factors. This only happens when the numbers are co-prime -- that is, when the numbers have only one common factor. In that case, the common factor is always 1.
Which pair of numbers has a greatest common factor that is a prime number 54 and 99 or 80 and 114?
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.
What two number pairs whose least common factor is the product of the number?
Any pair of prime or relatively prime numbers.
What pair of numbers has the greatest common factor of 1?
Numbers that are relatively prime, like 5 and 7 or 5 and 8.
What numbers have the least amount of factor pairs?
Prime numbers have one factor pair.
Which pair of numbers that has a great common factor that is a prime number 48 90 105 and 56?
56 and 105
