3.
HCF of 27,63,207
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.
factors of 8: 1, 2, 4, 8 factors of 18: 1, 2, 3, 6, 9, 18 HCF: 2
18
3 and 18 6 and 9
9= 3x3 12= 2x2x2x2x3 HCF = 3
The GCF is 9.
The GCF is 9.
