The GCF of 90 and 108 is 18.
The least common factor is 1.
obviously, its highest common factor is the number itself. so the answer here is 90.

There is no highest common multiple of any two or more numbers, for whatever multiple is stated, their LOWEST common multiple can be added to get an even higher common multiple. However, there is a highest common FACTOR (HCF) which is the largest positive number that divides all the numbers without a remainder, and a LOWEST common multiple (LCM) which is the smallest number into which all the numbers divide without a remainder. For 108, 54, 90: hcf(108, 54, 90) = 18 lcm(108, 54, 90) = 540

The GCF is 18.
The greatest common factor is 18
18 is the largest number that can divide into both 90 and 108 evenly.
The Greatest Common Factor (GCF) is: 18 .
