GCF of 36 and 90 is 18
What is the greatest common factor of 9, 18, and 15.The answer is....3
You need at least two numbers to find a GCF. If that's 4 and 9, the GCF is 1.
The highest common factor of 45 (forty-five) and 8 (eight) would equal to 1 (one). See: 45= 1 x 45 8= 1 x 8 3 x 15 2 x 4 5 x 9 Common Factor= 1 H.C.F. (Highest Common Factor)= 1
