1)LCM is 900
2)Not sure about this one, but it's possibly the associative property.

The lcm = lowest common multiple or in common words the lowest number that will divide into the three numbers in questions
( 12 , 18 , 75
step 1 dactor the three number ( break the number ubtil you can't
example
12 factors to 3 x 2 x 2 ( if you disn't noteice these factors ate prime numbers so when you factor a number you find zasll the prime factors )
18 factors to 3 x 3 x 2
75 factor to
5 x5 x 3
so you notice something look back over the factor of each number and see if you notice simrthing that appears in each of the factorizations ( it the 3 ) so 3 id the lcm ot 12 , 18 75
q2
it is the distributive property

The answer to #2 is the identity property of multiplication.
For all Real Numbers A
A*1=A

I can only answer the first one
12 = 2^2 * 3
18 = 2 * 3^2
75 = 3 * 5^2
LCM (12,18,75) = 2^2 * 3^2 * 5^2 = 900

LCM is 3
and the property is the distributive property
