To find the greatest common factor, or GCF, you must first identify the factors for each number.
For 150, its factors are 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, and 150.
For 225, its factors are 1, 3, 5, 9, 15, 25, 45, 75, and 225.
75 is the highest (or greatest) factor they have in common, so the GCF for 150 and 225 is 75
Oh, dude, the Highest Common Factor (HCF) of 150 and 225 is 75. It's like when you're trying to find the biggest number that can divide both 150 and 225 without leaving a remainder. So yeah, 75 is the winner here. Cool, right?
30 is the hcf of 150 and 240.
25
They are 1, 2, 3, 5, 6, 10, 15, 25, 45, 75, 150.
The GCF is 25.
The GCF/HCF of 360 and 225 is 45.
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 GCF/HCF of 100 and 225 is 25.
The GCF is 25.
It is: (225+150)/2 = 187.5
The GCF is 10.
The HCF is: 45
The GCF is 75.
