The GCF of two prime numbers is 1. 4, 9 and 25 are relatively prime.
Yes, e.g. 3 and 5 are relatively prime, 27 (33) and 25 (52) are relatively prime...
25 and 98 are not prime numbers
By definition, two numbers say a and b are relatively prime if and only if the gcd (a,b) = 1.The two pairs are (5, 16) and (16, 25).
If you don't include 20, 25 and 30, all of the numbers in that range are relatively prime to 25.
25 is relatively prime with 36. 25 is not relatively prime with 35.
Numbers having no common positive divisors other than one are relatively prime. In other words, the greatest common denominator of the numbers is one. Example: 24 and 25 are relatively prime.
No. Both are divisible by 5.
Two numbers are relatively prime if the only factor they have in common is 1. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 25 are 1, 5, and 10. The only factor they have in common is 1, so they are relatively prime.
Any pair of prime or relatively prime numbers.
Two numbers which are "relatively prime" have no common prime factors. To illustrate, let's write several numbers in terms of their prime factors: 24 = 2 x 2 x 2 x 3 25 = 5 x 5 42 = 2 x 3 x 7 70 = 2 x 5 x 7 You can see that 24 and 25 are relatively prime, because they don't share any common prime factors. Likewise, 25 and 42 are relatively prime. 24 and 42, however, are NOT relatively prime because they share the common factors of 2 and 3. Likewise 25 and 70 are NOT relatively prime because they share the common factor 5. When a fraction is in its simplest form, the numerator and denominator are relatively prime.
Such numbers are said to be "relatively prime". They may be two different prime numbers (e.g., 17 and 3); or they may simply have no prime factors in common (e.g., 25 and 14 - their prime factors are 5 x 5, and 2 x 7).
