It doesn't matter what method you use, you need at least two numbers to find a GCF.
Parenthesis, exponents, multiplication, division, addition, subtraction. PEMDAS
Pemdas means parentheses exponents Multipacation division Add Subtract Hope this helps :)
Algebra
to find a power of a product you add the exponents
The gcf is 3.
It doesn't matter what method you use, you need at least two numbers to find a GCF.
The GCF is 7.The LCM is 70.
It is 3 because 9/3 = 3 and 12/4 = 3
If the bases are the same then for division subtract the exponents to find the quotient

30/2 = 15/3 = 5/5 = 1 2 x 3 x 5 = 30
by long division
216 ,4587 and 2378
Two or more numbers are needed to find their LCM
Two or more numbers are needed to find their LCM
all you have to do is find the "least common multiple" witch is also the leats common denomenator
