GCF of 21 and 51 is 3.21=3*751=3*17
The common factors of 51 and 85 are: 1 and 17.
The common factors of 51 and 68 are: 1 and 17
The GCF of 21 and 51 is 3. Both these numbers have only one prime factorization. 21=3*7 51=3*17 So the greatest common divisor is 3.
The factors of 51 are 1, 3, 17, and 51. The factors of 119 are 1, 7, 17, and 119. The factors they have in common are 1 and 17. Therefore the greatest common factor is 17. The greatest common factor can also be determined from the prime factors. The prime factors of 51 are 3 and 17. The prime factors of 119 are 7 and 17. The prime factors they have in common are a single 17, so the greatest common factor is 17.
The factors of 21 are: 1, 3, 7, 21 The factors of 51 are: 1, 3, 17, 51
Factors of 51: 1, 3, 17, 51Factors of 21: 1, 3, 7, 21GCF (51, 21) = 3
GCF of 21 and 51 is 3.21=3*751=3*17
The factors of the two numbers are :- 51 : 1, 3, 17 and 51 21 : 1, 3, 7 and 21. Ignoring the trivial factor of 1, the only common factor and therefore the greatest common factor is 3.
The common factors of 51 and 85 are: 1 and 17.
The common factors of 51 and 68 are: 1 and 17
1 and 3 are the common factors of 51 and 15.
The common factors of 51 and 39 are 1 and 3.
51 and 16 share no common factors aside from 1.
The Least Common Multiple (LCM) for 51 21 is 357.
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.
