How do you find the gcf and lcm of 36, 40, and 45 using prime factorization?

36 = 2*2*3*3
40 = 2*2*2*5
45 = 3*3*5

There are no similar factors for all three. So the GCF is 1.

36 = 2^2 * 3^2
40 = 2^3 * 5
45 = 3^2 * 5

LCM is the product of the largest ammount of each prime that appears at least once.

2^3 * 3^2 * 5 = 8 * 9 * 5 = 360

Thats where they was ported and the fields that noone really knew much about needed tended, so they put slaves out there do free work and huge profits and so on the north decided to hold its own and was more different way of survival did not have same climate conditions to afford protecting slaves from winter so expenses be diff from south
