Gcf=3, lcm=9
They are gcf = 3 and LCM = 6
9 and 6 have an LCM of 18 and a GCF of 3.
GCF is 2.LCM is 42.The GCF is 2.
To find the GCF of 9x^2y and 39xy^3 first look at the GCF of 9 and 39 with is 3 Now the GCF of x^2 and x is x and the GCF of y^3 and y is y so the GCF of the 9x^2y and 39xy^3 is 3xy Use a similar idea to find the LCM. The LCM of x^2 and x is x^2 and the LCM of y^3 and y is y^3, lastly, the LCM of 9 and 39 is 117 so the LCM is 117x^2y^3
The GCF is 3. The LCM is 45.
To make this easier, let's first factor 18 and 21 into their prime factors: 18=2*3^2 21=3*7 Now it's very easy to find the LCM and GCF. The LCM is 2*3^2*7=126, and the GCF is 3.
The LCM of 16 and 2 is 16. The GCF is 2.
The GCF is 3. The LCM is 99.
Gcf= 3 lcm=78
LCM 21, and GCF =1
The LCM is 270. The GCF is 3.
