Do the following numbers share common factors? If so, which is the greatest?: {54, 32, 96}

Answer 1

Greatest common factor is #2#.

Factors of #54# are #{1,2,3,6,9,18,27,54}#
Factors of #32# are #{1,2,4,8,16,32}#
Factors of #96# are #{1,2,3,4,6,8,12,16,24,32,48,96}#
Common factors are just #{1,2}# and greatest common factor is #2#.

Answer 2

#GCF = 2#

If we only know the multiplication tables up to 12 x 12, we should be able to find the GCF fairly quickly in most situations.

In certain cases, such as this one, a larger number may be present that we are not familiar with. Mentally creating factor trees will enable you to write down all of the prime factors.

(for example: #96 = 8xx12 = 2xx4xx4xx3 = 2^5 xx3#

It is beneficial to have a backup plan in place in the event that visual inspection fails to locate the GCF.

Write each number as the product of its prime factors to find the GCF (and the LCM).

#color(white)(xxxx) 32 = 2xx2xx2xx2xx2# #color(white)(xxxx) 54 = 2color(white)(xxxxxxxxxxx)xx3xx3xx3# #color(white)(xxxx)96= 2xx2xx2xx2xx2xx3#
#GCF =color(white)(xx)2#

This makes it abundantly evident that there is only one common factor, which is 2. (I find this result surprising; I had anticipated a higher number.)

This format makes it simple to calculate the LCM if we need it: Add all the factors in each column, making sure not to count the same factors twice.

Answer 3

To determine if the numbers 54, 32, and 96 share common factors, we can find the prime factorization of each number and then identify the common prime factors.

  1. Prime factorization of 54: [ 54 = 2 \times 3^3 ]

  2. Prime factorization of 32: [ 32 = 2^5 ]

  3. Prime factorization of 96: [ 96 = 2^5 \times 3 ]

From the prime factorizations, we can see that all three numbers share the factor of 2. The greatest common factor among them is ( 2^5 = 32 ).

So, the numbers 54, 32, and 96 share common factors, with the greatest common factor being 32.

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.
