To find the HCF of two numbers you first need to identify their prime factors. In this case we have: 11 = 11 9 = 3x3 The next step would be to identify any common prime factors. In this case there are none. Thus the hcf of 11 and 9 is simply 1.
3.
what is the HCF for 11 33 121
The GCF is 11.
9 since 9 * 3 = 27 and 9 * 11 = 99
9= 3x3 12= 2x2x2x2x3 HCF = 3
The GCF is 9.
HCF of 27,63,207
The GCF is 9.
11
The HCF is 1.
