I suggest factoring each pair of numbers, and checking whether they have, or don't have, common factors. A pair of numbers is said to be "relatively prime" if they have no common factors (their greatest common factor is 1).
For larger numbers, Euclid's algorithm could be used, but for such small numbers, factoring is probably faster.
'Relatively Prime' simply means that two numbers have no common factors except 1 between each other. For example, two prime numbers would have no common factors between them. i.e., look at 3 and 10. There are no common factors between these 2 numbers.
27 and 81 are a possibility. Also numbers like 5 and 10, 20 and 40.
The two numbers 10 and -1: 10 × -1 = -10 10 + -1 = 10 - 1 = 9
There are 8 prime numbers between 10 and 40: 11 13 17 19 23 29 31 37.
The numbers need not have any common factor other than 1. For example, consider 2*5 = 10 and 3*7 = 21. 10 and 21 are both composite but their GCF = 1. They are said to be relatively prime or coprime. No.
No, they are not.
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
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.
No. Both are divisible by 5.
Two numbers are relatively prime if their greatest common divisor (GCD) is 1. In other words, there is no positive integer greater than 1 that divides both of the numbers. For example, 7 and 12 are relatively prime, but 10 and 15 are not, as their GCD is 5.
10 and 21
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.
Yes, they are relatively prime.
NO!!!! They are both compound numbers. . All even numbers are NON-primes , except '2'.
If the least common multiple of two numbers equals the product of the two numbers, then the numbers are relatively prime, that is their highest common factor is 1. For example, the numbers 10 and 21: The lcm is 10 x 21 = 210 They are relatively prime since their hcf is 1.
10 and 35 are not relatively prime because they share the prime factor 5.
Yes, the only common factor they share is 1.
