Answers
Answer:
lcm(81,82) = 6642
The lcm of 81 and 82 can be obtained like this:
The multiples of 81 are … , 6561, 6642, 6723, ….
The multiples of 82 are …, 6560, 6642, 6724, …
The common multiples of 81 and 82 are n x 6642, intersecting the two sets above, n\neq 0 \thinspace\in\thinspace\mathbb{Z}n
=0∈Z.
In the intersection multiples of 81 ∩ multiples of 82 the least positive element is 6642.
Therefore, the least common multiple of 81 and 82 is 6642
