It is not possible to give a sensible answer to this question. The highest common factor (HCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question!
The highest common factor of the numbers 210 and 330 is 30.
70
The HCF/GCF of 385 and 210 is 35.
The GCF is 14.
The GCF is 35.
The GCF is 14.
5. 5 | 210 525 | 42 105
The highest common factor of 60 and 210 is 30.
The GCF is 14.
The question is confusing me. In order to have a "common factor", we must be comparing two or more numbers, like comparing 210 with something else. If you just want the largest factor of 210, it'll be 210. Nancy
The GCF is 6.
The highest common factor of the numbers 294, 252 and 210 is 42.
