Numbers having only 1 as their common factor?
are co-prime
What are numbers called with only one factor?
The only number with a single factor is ' 1 '. Every other number has at least two factors: ' 1 ' and itself. A number with only those two factors and no others is called a "prime" number.
What numbers can go into 11 and 9?
The only common factor is one.
What is the greatest common factor of 348 and 426?
Start of by finding the prime factorization of both these numbers. 348=2²*3*29 426=2*3*71 The greatest common factor is going to be the product of all factors that both numbers share. The only two common factors between 348 and 426 are 2 and 3, so the greatest common factor is 2*3=6.
What are numbers with only 3 factors called?
they are called numbers with 3 factors
Is it possible for two numbers to have only one common factor?
Yes. Not counting one as a factor, you could have numbers like 6 and 10 which only share one common factor, 2.
Two numbers having only 1 as common factor is called?
They are called prime numbers.
Are 10 and 21 two relatively prime numbers?
Yes, the only common factor they share is 1.
What is the HCF prime factor of 48 64 and 80?
The only prime factor these numbers share is 2. It is the only prime factor of 64, which is 2 to the 6th power. The hcf is 16, but that is not a prime.
What are the common factors of 2 and 5 and 10?
This question cannot be answered as all three numbers do not share a common factor. 2 has 2 as its only factor 5 has 5 as its only factor 10 has 2 and 5 as its factors. As you can see the three numbers do not contain a common factor, but 10 does have both the other numbers as factors.
Numbers having only 1 as their common factor?
are co-prime
What is the greatest common factor between 6 and 9?
1, as the three numbers only share 1 as a factor.
What goes into 171 and 160 evenly?
The greatest common factor of these numbers is 1. If it were a composite number, we could say that that number, and all the numbers that divide it evenly, divide these numbers evenly. However, these numbers are relatively prime-that is, the only factor they share is 1.
What is the HCF of 2 and 1?
A factor of a number will divide that number evenly. A common factor is any factor which two numbers share. One of the numbers here is 1. The only number that can divide evenly in to is 1. Therefore, it doesn't matter what the other number is, the HCF can only be 1.
What is the greatest common factor of 17 an 11?
Both 17 and 11 are prime numbers, meaning the only numbers they can be divided by evenly are themselves and 1. This would mean the greatest common factor they share is 1.
What is the GCF of 3and 4and 5?
The only factor that all of these numbers share is 1 since 3 and 5 are prime. So 1 is the gcf of this set of numbers.
What is the greatest common factor of 34?
There cannot be a greatest common factor if there are not at least two numbers to compare. The greatest common factor is the largest factor that all the numbers have in common - the largest factor that they all share.
