Question

Find the greatest common factor of 6a^2b^2c^2d and 2acd^2 A. acd B. 2acd C. 2acd^2 D. 2a^2b^2c^2d^2

Answer 1

The greatest common factor of 6a^2b^2c^2d and 2acd^2 is 2acd "B."

Answer 2

Answer:

2acd

Explanation:

Ironically it is the lowest index which is the Greatest common factor. (You cannot get more from a term than what is there.)

Make sure that a particular base is in both terms and use the lowest power for the GCF.

2acd
There is no b factor in the second term, so it cannot be common.

The opposite happens when find the LOWEST common multiple . then it is the HIGHEST power which has to be used, because the LCM has to contain the whole of each term
