Divide 30 by 1, 2, 3 and 5.
10x - 30 10(x - 3) ------------
It can be. 30 is a factor of 60.
20 is not a factor of 30
30 is a factor of 150 so 30 is the greatest common factor of 30 and 150
Divide 30 by 1, 2, 3 and 5.
The greatest common factor (GCF) is 5.
The GCF is 3.
You need at least two numbers to find a GCF.
The square root of 900 is 30 and it is a factor of 900
You need more than one number to find a GCF.
Firstly, a factor of a number is another number that you can divide it by and get a whole number. The factors of 40 are: 1,2,4,5,8,10,20 and 40 The factors of 30 are: 1,2,3,5,6,10,15 and 30 Now, to find the GREATEST common factor of 40 and 30 , we would have to find the biggest number that goes into both 40 AND 30. After reading the factors above, we can see that 10 is the highest number that goes into both numbers, therefore 10 is the greatest common factor of 40 and 30.
Since 30 is a factor of 60, and the largest possible factor of 30 is 30, the greatest common factor is 30.
The GCF is 15.
The GCF is 5.
5
The GCF is 6.
