35 and 49, among others.
No.
No, 54 and 165 are not relatively prime.
Oh, isn't that a happy little math problem! To find the two prime numbers that equal 54, we gently divide 54 by the smallest prime number, which is 2. This gives us 27. Then, we continue to divide 27 by the next smallest prime number, which is 3. And there you have it, the two prime numbers that equal 54 are 2 and 3.
2 and 3
x+y=54 x-y=20 solving it,we get x=37 and y=17
No, two even numbers cannot be relatively prime.
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.
No.
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.
Yes
The two prime numbers that can be added together to make 54 are 7 and 47. Both 7 and 47 are prime, and their sum equals 54. There are no other pairs of prime numbers that also add up to 54.
No, 54 and 165 are not relatively prime.
Yes, 35 and 54 are relatively prime.
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
If two prime number have a sum of 54 they cannot have a sum of 84, and conversely.
