35 and 49, among others.
No, 54 and 165 are not relatively prime.
It is: 2*3*3*3 = 54
2 and 3 2x3x3x3= 54
23, 31
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
Relative prime-ness requires a set of two or more numbers to share the same positive integer factors and no others. Since the number 54 adds the factors 9, 18, and 27, to the factors of 12, the two numbers are not relatively prime.
No, two even numbers cannot be relatively prime.
Yes
No, they can both be divided by two. No two even numbers can be relatively prime.
54 and 99 are not prime numbers because they have more than two factors.
No, they are not relatively prime. They both have 2 as a common factor. If two or more numbers are relatively prime, that means those numbers have no factors in common except for 1.
35 and 49, among others.
No, 54 and 165 are not relatively prime.
Yes, 35 and 54 are relatively prime.
You can multiply the number 18 by different numbers that are relatively prime, for example by different prime numbers.
It can be. 40 is relatively prime to 41. 40 is not relatively prime to 54.
