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
9 and 6 have an LCM of 18 and a GCF of 3.
Gcf=3, lcm=9
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.
GCF is 2.LCM is 42.The GCF is 2.
2 x 3 = 6 2 x 5 = 10 The GCF is 2.
The LCM of 16 and 2 is 16. The GCF is 2.
2 x 3 x 3 = 18 2 x 2 x 5 = 20 The GCF is 2. The LCM is 180.
The GCF refers to whole numbers, not decimals.
96=2*2*2*2*2*3 108=2*2*3*3*3 They both have two 2s and one 3 in common. For GCF, multiply all the numbers that they have in common together. 2*2*3=12. For LCM, multiply the two given numbers together and divide that by the GCF. 96*108=10368, 10368/12=864. So GCF=12 and LCM=864.
GCF = 9To find the LCM, find the prime factorization of each number9y = 3 * 3 * y18x = 2 * 3 * 3 * xLCM = 2 * 3 * 3 * x * y = 18xy
The GCF is 3. The LCM is 99.
