Because it is the largest number that divides into both 6 and 15 evenly with no remainder.
The greatest common factor (gcf) of 15 and 6 is 3.Factors of 6:1,2,3,6Factors of 15: 1,3,5,15The greatest common factor of the numbers 6 and 15 is 3.The GCF of 6 and 15 is 3. This gives you 2 and 5 respectively. You cannot get any more common factors that impact the end figure.The GCF is 3.Greatest common factor of 6 and 15 is 3.
6
The GCF is 6.
The lowest common factor of 6 and 15 is 1. However, I suspect you either want their lowest common multiple (ie the smallest number into which both 6 and 15 divide) or their highest common factor (the largest number which will divided into both 6 and 15). LCM: 6 = 2 x 3 15 = 3 x 5 LCM = 2 x 3 x 5 = 30 HCF: 6 = 2 x 3 15 = 3 x 5 HCF = 3.
the greatest common factor of 6,12, and 15 is 3.
The least common factor is: 1
The GCF is 2.
The GCF is 6.
The GCF is 6.
3 x 6 = 18, 5 x 6 = 30; six is the largest common factor.
No. 6 is not a factor of 15. The greatest common factor of 15 and 18 is 3.
