The common factors of 21 and 51 are: 1 and 3
GCF of 21 and 51 is 3.21=3*751=3*17
The common factors of 51 and 68 are: 1 and 17
The common factors of 51 and 85 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 GCF of 21 and 306 is 3. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 21 are 1, 3, 7, and 21. The factors of 306 are 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, and 306. 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 factors of 21 are 3 and 7. The prime factors of 306 are 2, 3, 3, and 17. The prime factors in common are a single 3, so the greatest common factor is 3.
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.
