factors of 8: 1, 2, 4, 8 factors of 18: 1, 2, 3, 6, 9, 18 HCF: 2
HCF(8, 6) = 2.
The Highest Common Factor (HCF) of 6 and 18 is the largest number that divides both 6 and 18 without leaving a remainder. To find the HCF, we need to determine the common factors of 6 and 18, which are 1, 2, and 3. The largest among these common factors is 3, so the HCF of 6 and 18 is 3.

Prime factors of 6: 3x2 9: 3^2 Answer is 3
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.
They are 9 and 6
You need at least two numbers to find a GCF.

9= 3x3 12= 2x2x2x2x3 HCF = 3
The GCF is 9.
The GCF is 9.
The GCF is 6.
