1 and 3 are the common factors of 51 and 15.
The common factors of 21 and 51 are: 1 and 3
The common factors of 51 and 68 are: 1 and 17
The common factors of 51 and 85 are: 1 and 17.
The common factors of 51 and 39 are 1 and 3.
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
51 and 16 share no common factors aside from 1.
The factors of 51 are 1, 3, 17, 51 For them to be common, they need to be compared to another set of factors.
It depends upon the other number(s) with which 51 has common factors, but it will always be one of the factors of 51, namely 1, 3, 17 or 51.
The common factors of 24 and 51 are: 1 and 3
The greatest common factor is 51
The factors of 51 are 1, 3, 17 and 51. For them to be common, they need to be compared to another set of factors.
To find this you first have to identify the prime factors of each number. In this case they are: 15 = 3x5 51 = 3x17 The next step is to identify any common prime factors. In this case both numbers have a 3 as a prime factor. Therefore the HCF of 15 and 51 is 3.
