This is how you can work it out:
18: 1,2,3,6,9,18
(These are the numbers that 18 and 28 go into.)
28: 1,2,4,7,14,28
So the highest common factor of 18 and 28 is 2.
Hope it helps :)
The GCF is 3.
factors of 8: 1, 2, 4, 8 factors of 18: 1, 2, 3, 6, 9, 18 HCF: 2

The Highest Common Factor (HCF) of 90 and 126 is the largest number that divides both 90 and 126 without leaving a remainder. To find the HCF, we need to determine the common factors of 90 and 126, which are 1, 2, 3, 6, 9, and 18. The largest number among these common factors is 18. Therefore, the HCF of 90 and 126 is 18.
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.
The GCF is 28.
The Highest Common Factor (HCF) of 18 and 30 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, we need to determine the common factors of 18 (1, 2, 3, 6, 9, 18) and 30 (1, 2, 3, 5, 6, 10, 15, 30) and identify the largest one they share, which is 6. Therefore, the HCF of 18 and 30 is 6.
HCF = 3... LCM = 18 !
The GCF is 3.
The GCF is 18.
The GCF is 9.
4 and 336, respectively.
6 is the HCF of 18 & 48
The GCF is 6.
The HCF is 18
The hcf is 12
If you mean 28, 49 and 84 then the hcf is 7
