No, 51 isn't prime. 17 is the largest prime factor of 306.
Factor tree for 51: 51 * 1 or 17 * 3 Factor tree for 255: 255 * 1 or 51 * 5
Yes. 255/5 = 51.
Factors of 51: 1 3 17 51 Factors of 255: 1 3 5 15 17 51 85 255 The GCF of 51 and 255 is 51
1, 3, 5, 15, 17, 51, 85, 255
3 is a factor of 51, and 3 is also the largest factor of itself, so 3 is the greatest common factor. The factors of 3 are 1 and 3. The factors of 51 are 1, 3, 17, and 51. The common factors are 1 and 3. Therefore, the greatest common factor is 3. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factor of 3 is 3. The prime factors of 51 are 3 and 17. The common prime factors are a single 3, so the greatest common factor is 3.
The factors of 255 are:1 3 5 15 17 51 85 255The prime factors are: 3 x 5 x 171, 3, 5, 15, 17, 51, 85, 255
Basically factorise 255 and 256 separately. i.e. what prime numbers multiply together to give you 255 first 5 divides in (which is prime) to give you 51 then 51/3 =17 i.e. 5,3,17 = factors of 255 and 2,2,2,2,2,2,2,2 are factors of 256. The answer is 1 because you cant multiply 5,3 and 17 to give you an even number which is all you can get by multiply 2,2,2 etc. Thus ANSWER Is 1
No, 51 is not a prime number. A prime number is a number that has only itself and 1 as a factor. 51's factors are 1,3,17, and 51.
