That would be 15. Only a number ending in five would be a factor of 75. 45 is not. 35 is not. 25 is not. 15 is, and it also is a factor of 90. This makes it the highest common factor of 75 and 90, although it is not a prime factor.
Their greatest common factor is 15
HCF = 15

The greatest common factor of the numbers 60 and 75 is 15.
1 and the highest common factor is 15
The highest common factor of 60 and 75 is 15
15 is the highest common factor because 1 x 15 = 15 and 5 x 15 =75
It is: 15
