What are the gcf of number 15 and 45
The greatest common factor of the numbers 15 and 11 is 1.
To find two numbers with a greatest common factor (GCF) of 15 and a least common multiple (LCM) of 270, we can use the relationship between GCF, LCM, and the two numbers. The relationship is LCM(a,b) = (a * b) / GCF(a,b). Given GCF = 15 and LCM = 270, we can substitute these values into the formula to get 270 = (15 * b) / 15. Solving for b gives us b = 270 / 15 = 18. Therefore, the two numbers are 15 and 18.
10 and 15
You need at least two numbers to find a GCF.
15, 30, 45
the answer is 45 60 and 90
15 and 30
15, 30 and 45 have a GCF of 15.
the answer is 45 90 and 60
15, 30, 45 and 60
The GCF of the given three numbers is 1
The GCF of 9 and 15 is 3. The LCM is 45.
15 + 9 = 24 gcf (15,9) = 3 18 + 6 = 24 gcf(18,6) = 6 6 - 3 = 3
7 is not the greatest common factor (GCF) of 15, 30, and 35 because 7 does not evenly divide into all three numbers. The GCF is the largest number that can divide all three numbers without leaving a remainder, and in this case, the GCF is actually 5 since 5 divides evenly into all three numbers.
The GCF is 5.
Since 15 is a factor of 45, it is automatically the GCF.
