How do you find the greatest common factor of 14 42 91?

Answer 1

Gabriel Agustin

#7# is greatest common factor.

First write each number as a product of prime numbers. Here we have #14#, #42# and #91# and their prime factors are

#14=2×7#

#42=2×3×7#

#91=7×13#

Now list all the common factors (if any prime is occurring more than one time in each number pick up as many times it is spearing in all the numbers).

In above case, however, we have just #7#, which repeats in all.

Hence, here #7# is greatest common factor.

To find the greatest common factor (GCF) of 14, 42, and 91, you can use prime factorization method.

Step 1: Find the prime factorization of each number:

14 = 2 * 7
42 = 2 * 3 * 7
91 = 7 * 13

Step 2: Identify the common prime factors among the numbers. In this case, the only common prime factor is 7.

Step 3: Multiply the common prime factors together to find the GCF. GCF = 7

Therefore, the greatest common factor of 14, 42, and 91 is 7.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
