15, 30 and 45.
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
75 = 3*5*5, so the first pair that comes to mind is 3*5 and 5*5.LCM(15, 25) = 75.And it conveniently happens to be that GCD*(15, 25) = 5.So {15, 25} is the answer (at least an answer).*GCD is "Greatest Common Divisor" and a more official way of saying GCF.* * * * *Yes, it is an answer.Consider LCM/GCF = 75/5 = 15If p and q are any two coprime factors of LCM/GCF = 15, then p*GCF and q*GCF will be an answer.The above answer used p = 3 and q = 5.The other possible pair is p = 1 and q = 15 which gives the pair as 5 and 75.
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.
