hcf(5, 15) = 5 lcm(5, 15) = 15.
hcf is 1 and LCM is 35
The GCF is 3. The LCM is 120.
18 = 2 * 3 * 370 = 2 * 5 * 7Thus:LCM = 2*3*3*5*7 = 630HCF = 2
hcf(300, 525) = 75 lcm(300, 525) = 2100 Using prime factorization: 300 = 2² x 3 x 5² 525 = 3 x 5² x 7 hcf = 3 x 5² = 75 lcm = 2² x 3 x 5² x 7 = 2100
HCF = 3... LCM = 18 !
hcf(5, 15) = 5 lcm(5, 15) = 15.
hcf = 15 lcm = 3510 270 = 2 x 33 x 5 195 = 3 x 5 x 13 hcf = 3 x 5 = 15 lcm = 2 x 33 x 5 x 13 = 3510
hcf is 1 and LCM is 35
5 and 10 lcm- 10 and hcf= 5
hcf(14, 30) = 2 lcm(14, 30) = 210 14 = 2 x 7 30 = 2 x 3 x 5 hcf = 2 lcm = 2 x 3 x 5 x 7 = 210
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.
Two or more numbers are needed to solve for HCF or LCM.
lcm(9, 12) = 36; hcf(9, 12) = 3.
No, that is the HCF. The LCM is 1800
