the hcf or gfc is 3
The GCF is 18.
The HCF is: 3
HCF is 3
hcf(18, 30) = 6.
HCF = 3... LCM = 18 !
The GCF is 18.
The GCF is 3.
The GCF is 18.
The HCF of the numbers 18 and 40 is 2.
The GCF is 9.
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.
6 is the HCF of 18 & 48
