There is no relatively prime number for 10. Relatively Prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.
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 30 a relatively prime number?
A number cannot be relatively prime number by itself. It can only be relatively prime in the context of (relativeto) another number. That requires the two numbers not to have any prime factors in common.
What number is relatively prime to 10?
10=2*5 Any number that doesn't have a factor of 2 or 5 is relatively prime to 10. e.g. 3, 7, 11, and 21 are all relatively prime to 10. 2, 5, 15, 16, and 20 are not relatively prime since they share a factor or 2 or 5 (or both, which means they share a factor of 10, e.g. 20).
What are two possible pairs of number that have a GCF of 5?
