Yes.
Yes, they are relatively prime.
Two numbers are relatively prime if the only factor they have in common is 1. Example: 12 and 17 are relatively prime because they have only 1 as a common factor. 12 and 21 are not relatively prime because they have 1 and 3 as common factors.
Yes, 4 and 21 are relatively prime. Numbers that are relatively prime only have the number 1 as a common factor. That is the case with 4 and 21.
17 is a prime number, but 21 is not (21 = 3 * 7).
The prime numbers between 10 and 21 are 11, 13, 17, and 19.
hcf(10, 21) = 1 ⇒ 10 & 21 relatively prime hcf(12, 54) = 6 ⇒ 12 & 54 not relatively prime hcf(15, 27) = 3 ⇒ 15 & 27 not relatively prime hcf(21, 38) = 1 ⇒ 21 & 38 relatively prime
It can be. 21 is relatively prime with 32.
Four. The prime numbers between 10 and 21 are 11, 13, 17, and 19.
The prime numbers from 1 to 21 are 2, 3, 5, 7, 11, 13, 17, and 19.
Trivially not, since both of them are divisible by 3.
The prime numbers between 2 and 21 are: 2, 3, 5, 7, 11, 13, 17 and 19
The GCF of 17 and 21 is 1Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 17 are 1 and 17.The factors of 21 are 1, 3, 7, and 21.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.1 because 17 is a prime number
