The GCF is 1.
First you have to find the GCF (Greatest Common Factor) of 28 and 30, which is 2, so then you divide 2 by 28 and 30, and get 14 over 15. Hoped this helped!
Find out all the factors and then find the greatest common factor (gcf)...........very easy
You need at least two numbers to find a GCF.
The GCF is 2.
The GCF of 15 and 28 is 1. GCF stands for greatest common factor.
The GCF of 15 and 28 is 1. The factors of 15 are 1, 3, 5, and 15 The factors of 28 are 1, 2, 4, 7, 14, and 28 So the GCF of 15 and 28 is 1
15 - 1, 3, 5, 15 28 - 1, 2, 4, 7, 14, 28 The GCF is 1
21 and 28
The greatest common factor of 15, 28 and 35 is 1.
The GCF is 1.
The GCF is 1.
1.
The GCF is 1.
The GCF of 14 and 28 is 14. Since 14 is a factor of 28, it is automatically the GCF.
33 = 3x11 288 = 2x2x2x2x2x3x3 gcf = 3
The GCF is 3.
