27/3 = 9 and 51/3 = 17 so three is the greatest common factor (it's the only)
Common factors of 17 and 102 are: 1 and 17.
17's prime so 1
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 GCF is 17.
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 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 GCF is 3.
The GCF is 1.
Factor them. 3 x 17 = 51 5 x 17 = 85 Select the common factor. The GCF is 17.
27/3 = 9 and 51/3 = 17 so three is the greatest common factor (it's the only)
Common factors of 17 and 102 are: 1 and 17.
17's prime so 1
The GCF is 1.
There is not a greatest common factor of 51 because there cannot be a greatest common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common.The factors of 51 are 1, 3, 17, and 51.Examples:The greatest common factor of 34 and 51 is 17.The greatest common factor of 51 and 90 is 3.The greatest common factor of 5 and 51 is 1.You need at least two numbers to find a GCF.
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 GCF of 51 and 69 is 3. 3 x 17 = 51 3 x 23 =69 so the greatest common factor is 3
