The common factors are: 1, 7
A factor is a divisor - a number that will evenly divide into another number. 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 35 are 1, 5, 7, and 35. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The common factors are 1 and 7.
They are 1 and 7
The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 35 are 5 and 7. The prime factors of 42 are 2, 3, and 7. The common prime factors are a single 7, so the greatest common factor is 7.
-- The factors of 12 are 1, 2, 3, 4, 6, and 12 .-- The factors of 35 are 1, 5, 7, and 35 .-- The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42 .-- The common factors of 12, 35, and 42 are 1, . . . oh, there aren't any others besides ' 1 '.
Greatest common factor= 7 The greatest common factor is the factor that all these numbers have in common. It helps to make a list of all the number's factors. 28- 2, 2, 7 35- 5, 7 42- 2, 3, 7 All of these numbers have 7 as a factor, therfore 7 is the greatest common factor
The factors of 35 are:1, 5, 7, 35The factors of 42 are:1, 2, 3, 6, 7, 14, 21, 42The common factors are:1, 7The Greatest Common Factor (GCF) is:7
The common factors are: 1, 7
The highest common factor of all four numbers is 7
The GCF of 42 and 35 is 7.factors of 42: 2,6,7factors of 35: 5,7
The common factors of 21 and 42 are 1,3,7,21
The common factors of 42 and 273 are 1, 3, 7 and 21.
The common factors of 22 and 42 are: 1 and 2
