Final answer:
To find the 2 factor pairs that have an LCM of 90 and a product of 810, list the factors of 90 and see which pairs multiply to 810. The factor pairs are (6, 135) and (10, 81).
Step-by-step explanation:
To find the 2 factor pairs that have an LCM of 90 and a product of 810, we need to list the factors of 90 and see which pairs multiply to 810.
The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.
When we multiply each factor by 90, we get the product.
The factor pairs that have an LCM of 90 and a product of 810 are (6, 135) and (10, 81).
