Question 388866
Re these seperate??

If not you have the option of finding the GFC, LCD, or LCM

The GFC:


[11-3][-2-18]_3[323]+4[422]_[7-16][363]

Subtract 3 from 11 to get 8.
[8][-2-18]+3[323]+4[422]+[7-16][363]

Subtract 18 from -2 to get -20.
[8][-20]+3[323]+4[422]+[7-16][363]

Subtract 16 from 7 to get -9.
[8][-20]+3[323]+4[422]+[-9][363]

Multiply 8 by -20 to get -160.
[-160]+3[323]+4[422]+[-9][363]

Multiply 3 by each term inside the parentheses.
[-160]+969+4[422]+[-9][363]

Multiply 4 by each term inside the parentheses.
[-160]+969+1688+[-9][363]

Multiply -9 by 363 to get -3267.
[-160]+969+1688+[-3267]

Remove the parentheses that are not needed from the expression.
-160+969+1688-3267

Add 969 to -160 to get 809.
809+1688-3267

Add 1688 to 809 to get 2497.
2497-3267

Subtract 3267 from 2497 to get -770.
Answer:  -770



The LCD

[11-3][-2-18]_3[323]+4[422]_[7-16][363]

Since there are no fractions, and therefore no denominators, the least common denominator is 1.  Since this has no fractions, try to find the LCM of this set of expressions.
1




The LCM


[11-3][-2-18]_3[323]+4[422]_[7-16][363]

The LCM of [11-3][-2-18],3[323]+4[422],[7-16][363] is 12[-2-18][11-3][422][363][7-16][323].
Answer:  12[-2-18][11-3][422][363][7-16][323]
