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
255 x 2 = 510
The GCF of 255 and 256 is 1.
The largest number that goes into 150, 160, and 255 is 5.
