Co-prime or relatively prime
are co-prime
Numbers with only one factor are called prime numbers. A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. Examples of prime numbers include 2, 3, 5, 7, 11, and so on. These numbers have only two factors: 1 and the number itself.
The only common factor is one.
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.
they are called numbers with 3 factors
Yes. Not counting one as a factor, you could have numbers like 6 and 10 which only share one common factor, 2.
They are called prime numbers.
Yes, the only common factor they share is 1.
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.
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.
are co-prime
1, as the three numbers only share 1 as a factor.
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.
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.
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.
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.
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.
