The common factors of 18, 30, and 42 are: 1, 2, 3, and 6The Greatest Common Factor (GCF) is: 6
The GCF is 1.
Greater than what? As every number has a factor of 1, there is always a common factor of 1 between any two numbers; if there are no other common factors then the greatest common factor of those numbers is 1. The factors of 154 and 42 are: 154: 1, 2, 7, 11, 14, 22, 77, 154 42: 1, 2, 3, 6, 7, 14, 21, 42 Their common factors are: 1, 2, 7, 14 Therefore their greatest common factor is 14.
42 prime factors -----> 2,3,7 105 prime factors -----> 3,5,7 There is 3 and 7 in common : There fore 3*7 = 21; 21 is the greatest common factor.
2 ist greatest common factor
The GCF is 14.
Greatest common factors of 7 42 & 70 is 7.
The greatest common factor of 42 depends upon the other numbers with which 42 has COMMON factors. However, the greatest common factor HAS to be one of the factors of 42 which are: 1, 2, 3, 6, 7, 14, 21, 42.
The GCF of 42 and 86 is 2. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 86 are 1, 2, 43, and 86. The common factors are 1 and 2. Therefore, the greatest common factor is 2.
The common factors of 21 and 42 are 3, 7 and 21. The greatest common factor (GCF) is 21.
There is neither a greatest common factor nor common factors of a single number, such as 42, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. Examples: The common factors of 25 and 42 are only 1; the greatest common factor is 1. The common factors of 36 and 42 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 42 and 49 are 1 and 7; the greatest common factor is 7. The common factors of 42 and 60 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 42 and 70 are 1, 2, 7, and 14; the greatest common factor is 14.

Factors of 28... 1,2,4,7,14,28 Factors of 42... 1,2,3,6,7,14,21,42 GCF = 14
The greatest common factor of 25 and 42 is 1 because it is the only common factor.
