A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 160 are 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, and 160. The factors of 256 are 1, 2, 4, 8, 16, 32, 64, 128, and 256. The common factors are 1, 2, 4, 8, 16, and 32. Therefore, the greatest common factor is 32.
That is incorrect. The common factors of 500 and 256 are 1, 2, 4.
1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400...
256 is not prime. 256 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2
256
Well, well, well, aren't we feeling all mathematical today? The greatest common factor of 16 and 256 is 16. It's like finding out you have a favorite child - sorry 256, but 16 takes the cake this time.
The least common multiple for 196, 225 and 256 is 2,822,400
The greatest common factor is the highest number that divides exactly into two or more numbers. 256: 1, 2, 4, 8, 16, 32, 64, 128, 256 625: 1, 5, 25, 125, 625, The GCF for 256 and 625 is 1.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 384 and 512 is 128
Since 16 is a factor of 256, all of its factors are common.
Common factors of 286 and 242 are: 1, 2, 11, and 22.
The GCF of 256 and 352 is 32
The greatest common factor of 286 and 251 is 1.
256 + 225 - 196 + 169 = 454
It is: 4
It is: 16
It is 64
