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 28.
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.
4 and 336, respectively.
6 is the HCF of 18 & 48
The GCF is 6.
The HCF is 18
