What is the greatest common factor of 49 and 42?

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


What is the greatest common factor of 21 42 49?

To find the greatest common factor of 21, 42, and 49, we first need to find the prime factors of each number. The prime factors of 21 are 3 and 7, the prime factors of 42 are 2, 3, and 7, and the prime factors of 49 are 7 and 7. The greatest common factor is the product of the common prime factors raised to the lowest power they appear in any of the numbers, which in this case is 7. Therefore, the greatest common factor of 21, 42, and 49 is 7.


What is the greatest common factor of 42?

There is not a greatest common factor of 42 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 greatest common factor is the largest factor that all the numbers being compared have in common. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The prime factors of 42 are 2, 3, and 7. Examples: The greatest common factor of 36 and 42 is 6. The greatest common factor of 42 and 91 is 7. The greatest common factor of 42 and 375 is 3.

What are the common factors and greatest common factor of 42?

The common factors of 42 are the numbers that can evenly divide 42 without leaving a remainder. The common factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The greatest common factor (GCF) of 42 is the largest number that can divide 42 and another number without leaving a remainder. In this case, the GCF of 42 and any other number would be 42 itself.
