Answer:
We will discuss here about the method of l.c.m. (least common multiple).
Let us consider the numbers 8, 12 and 16.
Multiples of 8 are → 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, ......
Multiples of 12 are → 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, ......
Multiples of 16 are → 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, ......
The common multiple of 8, 12, 16 are 78, 96, ......
The least common multiple of 8, 12 and 16 is 48. (Smallest common multiple)
In short, the lowest common factor is expressed as L.C.M.
Finding L.C.M.
To find the L.C.M. we find prime factors of the given numbers.
Remember, we consider common prime factors only.
