The GCF is 7.
The GCF of 7 and 28 is 7.
The lcm of 28 and 49 is 196. The gcf of 28 and 49 is 7.
For 28 and 49:The LCM is: 196The GCF is: 7
We know the gcf x LCM= AB where A and B are the two numbers. So the product of the two number we seek is 196 7 and 28 have a product of 196 and the gcf of 7 and 28 is 7. The LCM of 28 and 7 is 28. So the two numbers are 7 and 28. ( I started out by dividing 196 by 7 to get the 28)
Since 7 is a factor of 28, it is automatically the GCF.
The GCF of 28, 84, and 91 is 7.
7 is the gcf of 28 35 and 42
GCF(14, 28, 21) = 7
