what is the greatest common factor of 106 and 320
http://computerscience.jbpub.com/cryptography/TestGCDApplet.cfm
106 = 2*53
320 = 2 * 160 = 2*2*80 = 2*2*2*40=2*2*2*2*20= 2*2*2*2*2*10 =2*2*2*2*2*2*5
so
2
To find the greatest common factor of two numbers, you can start by identifying all the factors of each number separately.
For 106:
The factors of 106 are 1, 2, 53, and 106.
For 320:
The factors of 320 are 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, and 320.
Now, we need to find the factors that these two numbers have in common. From the factors listed above, we can see that both 106 and 320 have the factors 1 and 2 in common.
Therefore, the greatest common factor (GCF) of 106 and 320 is 2.
