The greatest common factor (GCF) of 9, 15, and 21 is 3. To find the GCF, you need to determine the factors of each number and then identify the largest factor that is common to all three numbers. The factors of 9 are 1, 3, and 9; the factors of 15 are 1, 3, 5, and 15; and the factors of 21 are 1, 3, 7, and 21. The largest factor that is common to all three numbers is 3, making it the greatest common factor.
Any polynomial in which there are at least two co-prime coefficients will have 1 as the greatest monomial factor.
15 and 37 are co-prime because they have no common factor greater than 1.
If the greatest common factor is 1, then the numbers are said to be co-prime or relatively prime.
No. 15 and 5 share the factor 5.
They are said to be relatively prime or co-prime.
