18 = 2 * 3 * 370 = 2 * 5 * 7Thus:LCM = 2*3*3*5*7 = 630HCF = 2
The GCF is 3. The LCM is 120.
In these types of problems, the numbers can also be the answer. 6 and 72 have a GCF of 6 and an LCM of 72. Since the product of the GCF and LCM of two numbers is the same as the product of the numbers, you could also use another factor pair of 432, like 18 and 24.
hcf is 1 and LCM is 35
HCF is 48 and LCM is 576
HCF = 3... LCM = 18 !
18 and 3
3 and 18 do.
LCM=18=2*32 HCF(guess that is what u meant, highest common factor)=3 Possibilities: 3 and 18, 6 and 9, three or all of the numbers together. Note: 3 and 6 gives a LCM of 6 3 and 9 gives a LCM of 9 6 and 18 gives a HCF of 6 9 and 18 gives a HCF of 9 Three or four out of the numbers (3,6,9 and 18) will give you LCM of 18 and HCF of 3 as well.
3 and 18
Factors: 15 = 3 x 5, 18 = 2 x 3 x 3. The LCM of two numbers = their product divided by their HCF. In this instance the product is 270 and the HCF is 3 so the LCM is 90.
They are 9 and 6
3 and 18 6 and 9
The LCM is: 126
Two or more numbers are needed to solve for HCF or LCM.
18 = 2 * 3 * 370 = 2 * 5 * 7Thus:LCM = 2*3*3*5*7 = 630HCF = 2
lcm(9, 12) = 36; hcf(9, 12) = 3.
