The answers:
LCM=9000
GCF=50
The explanations:
To do these types of questions, break each number down into its prime factors:
450 = 2*3*3*5*5
1000=2*2*2*5*5*5
Now the LCM will be product of all the prime factors in 450 and 1000 altogether: 2*2*2*3*3*5*5*5 = 9000
The GCF will be the product of the prime factors which occur in BOTH 450 and 1000: 2*5*5 = 50
Hope that helps.

gcf = 50
lcm = 9000
Since 1000 = 2^3*5^3 and 450 = 2*3^2*5^2, the gcf is = 2*5^2=50(the greatest powers of each common prime factor multiplied) and the lcm = 2^3*3^2*5^3=9000

1000 = 2*2*2*5*5*5
450 = 2*5*5*9
One 2 and two 5's are common
GCF = 2*5*5 = 2*25 = 50
lcm = 9000
