The GCF is 1.
Two numbers are relatively prime if they have no factors in common other than 1. This means their greatest common factor (GCF) is 1. Here are examples of pairs of numbers that are relatively prime: 2, 9 5, 14 13, 998 3, 379 37, 303 691, 701 32, 81 384, 625 Here are examples of pairs of numbers that are not relatively prime: 2, 8 (GCF: 2) 16, 1060 (GCF: 4) 52, 117 (GCF: 13)
The least common factor of any set of numbers is 1, so your problem won't work. 3, 5 and 10,15 have an LCM of 15. 15, 30 and 45,60 have a GCF of 15.
2^3 x 3^2 x 5 = 360 You need at least two numbers to find a GCF.
The prime factors of 75 are 3,5,5 as 3*5*5=75. This can be determined by testing 75 for divisibility by prime numbers starting from 2. Using the prime factorization you can determine that all the factor pairs are (3*5)*5=15*5 and 3*(5*5)=3*25

The GCF is 1.
None of those pairs has a GCF of 15.
The greatest common factor of 3 and 5 is 1. This is because 1 is the largest positive integer that divides both 3 and 5 without leaving a remainder. Since 3 and 5 are both prime numbers, their only common factor is 1.
The only factor that all of these numbers share is 1 since 3 and 5 are prime. So 1 is the gcf of this set of numbers.

Try 5, 10 and 15.
You need at least two numbers to find a GCF. If that's 3 and 15, the GCF is 3.
No. The GCF of 3 and 5 is 1. The GCF of 3 and 9 is 3.
The GCF of 5 and 10 is 5.
The GCF is 5.
factor out both numbers to get 102=2*3*17 50=2*5*5 the GCF is 2
