The GCF of 255 and 256 is 1.
It is 17 followed by 5 and 3
You need at least two numbers to find a GCF.
The factor pairs of 260 are (260,1), (130,2), (65,4), (52,5), (26,10), and (20,13)
The greatest common factor of 120 and 245 is 5.
68 = 2 * 2 * 17 255 = 3 * 5 * 17 So it is 17.
Factor tree for 51: 51 * 1 or 17 * 3 Factor tree for 255: 255 * 1 or 51 * 5
Yes. 255/5 = 51.
The greatest common factor of 85 and 255 is 85.
5x3x17
255 = 3 x 5 x 17
1, 3, 5, 15, 17, 51, 85, 255
5
255/2 doesn't work. So we need to get to the next number which is 255/3. Equals to 85. 85/2 is not gonna work, 85/3 too, 85/4 but 85/5 will work and it is equals to 17. There is no other factor for 17 except for 17 and 1. So the final answer is 3 * 5 *17
The largest number that goes into 150, 160, and 255 is 5.
The largest number that goes into 150, 160, and 255 is 5.
The GCF of 255 and 256 is 1.
