The GCF is 7.

One way to approach this is to look at the difference between 42 and 49, which is 7. The greatest common factor of two numbers cannot be larger than the difference between the two numbers and must be a factor of the difference. Since both 42 and 49 are divisible by 7, the greatest common factor is 7. Another way to determine the 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 49 are 1, 7, and 49. The common factors are 1 and 7. Therefore, the greatest common factor is 7. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 42 are 2, 3, and 7. The prime factors of 49 are 7 and 7. The prime factors in common are a single 7, so the greatest common factor is 7

42 and 49 7 x 6 = 42 7 x 7 = 49

Common factors of 49 and 77 are: 1 and 7.

Common factors of 49 and 112 are: 1 and 7.

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.

The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42The factors of 98 are: 1, 2, 7, 14, 49, 98The common factors are: 1, 2, 7, 14The Greatest Common Factor (GCF) is: 14

The factors of 98 are 1, 2, 49, 98 The factors of 42 are 1, 2, 3, 14, 21, 42. The GCF of 98 and 42 is 2.

Since 49 is a factor of 98, and the largest possible factor of 49 is itself, the greatest common factor is 49.One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 49 are 1, 7, and 49.The factors of 98 are 1, 2, 7, 14, 49, and 98.The common factors are 1, 7, and 49. Therefore, the greatest common factor is 49.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 49 are 7 and 7.The prime factors of 98 are 2, 7, and 7.The prime factors in common are 7 and 7, so the greatest common factor is 7 x 7 = 49.It is: 49
