You need at least two numbers to find a GCF.
The GCF is 3.
0.945
21 goes into 126 6times 21 goes into 189 9times gcf =21
The GCF is 27.
1+1=1 is the GCF of 189 and 200
The GCF is 1.
The GCF is 1.
You need at least two numbers to find a GCF.
The GCF is 27.
The GCF is 63.
The GCF is 9.
The GCF is 27.
The GCF is 27.
GCF(105, 145, 189) = 1: the three are coprime.
225=3^2x5^2 189=3x7x9 Therefore GCF(225, 189) = 3
3 x 3 x 3 x 7 = 189 2 x 2 x 2 x 5 x 5 = 200 No common prime factors; the GCF is 1.
