What else can I help you with?
Are 4 and 21 relatively prime?
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.
Are 7 and 21 relatively prime?
27 is not a prime number and i dont know about 117 but i dont think its a composite # * * * * * The person who gave the above answer has no understanding of "relative primes". Or primes, for that matter. Neither 8 nor 9 is a prime BUT 8 and 9 are relatively prime (or co-prime) because they have no factor in common. That is what relatively prime means. 117 is not a prime, even if the previous answerer thinks otherwise. 27 and 117 are not relatively prime because both are divisible by 3.
What is the greatest common factor of 21 and 121?
The greatest common factor of 21 and 121 is 1. (21 and 121 are relatively prime.)
Are 100 and 202 relatively prime?
No, 100 and 202 are not relatively prime. Relatively prime numbers only have the number 1 as a common factor. The number 1 is a common factor for them, but the number 2 is another common factor that they have, so they are not relatively prime.
What is a composite number that is relatively prime to 210?
209 is relatively prime (as is 211).
Are 21 and 44 relatively prime?
Yes, they are relatively prime.
Are 10 and 21 relatively prime?
Yes, they are relatively prime.
Are 20 and 21 relatively prime?
Yes, they are relatively prime.
Is 4 and 21 relatively prime?
Yes, they are relatively prime.
Are 16 and 21 relatively prime?
Yes, they are relatively prime.
Why is 17 relatively prime with 21?
Yes, they are relatively prime.
Are 21 and 88 relatively prime?
Yes, they are relatively prime.
Are 14 and 21 relatively prime?
No, 14 and 21 are not relatively prime. They share the factor 7.No.
Are 4 and 21 relatively prime?
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.
I need to know which pair of numbers in relatively prime 10 and 21 or 12 and 54 or 15 and 27 or 21 and 38?
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
Is 7 and 21 relatively prime?
No.
Is 21 and 72 relatively prime?
No.
