what is the greatest common factor of the numbers using prime factorization inc. whether the numbers are relatively prime: 168, 180 and 450?

Question

anonymous · Answer

clearly not relatively prime because they are all even

anonymous · Answer

$$168=2^3\times 3\times 7$$
$$180=2^2\times 3^2\times 5$$
$$450=2\times 3^2\times 5^2$$

anonymous · Answer

for least common multiple you will need 
$$2^3$$
$$3^2$$
$$5^2$$ and 
$$7$$
each factor you see to the highest power you see it in any ONE number

anonymous · Answer

so LCM is 
$$2^2\times 3^2\times 5^2\times 7$$ whatever that is

ok, thanks
