The GCF is 18.
HCF is 3
The HCF is: 3
hcf(18, 30) = 6.
HCF = 3... LCM = 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.
The GCF is 18.
The GCF is 3.
The GCF is 18.
The GCF is 9.
6 is the HCF of 18 & 48
The GCF is 6.
