17 and 306, respectively.
17
lcm(9, 12) = 36; hcf(9, 12) = 3.
The LCM is: 34
The GCF/HCF of 34 and 170 is 34.
HCF means the highest common factor of two or more numbers. LCM means the lowest common multiple of two or more numbers.
LCM(68, 102) = 204 HCF(68, 102) = 34
1394
It is: 34+7140 = 7174
The HCF is 2 The LCM is 986
48
LCM is 20 and the hcf is 10
The HCF is: 2The LCM is: 2,520
HCF is 60 and the LCM is 360
HCF = 3... LCM = 18 !
hcf = 42, lcm = 84.
HCF is 48 and LCM is 576
To work this out, you first have to give the numbers as their prime factors: 6 = 2x3 34 = 2x17 The next step is to identify the HCF. In this case, the HCF is 2. Finally, you multiply the numbers together and divide by the HCF: 6x34/2 = 102
