LCM( 49, 25, 16 ) = 19600
Step 1 : Place the numbers inside division bar:
49 | 25 | 16 |
Step 2 : Find a prime number which can divide at least two of your numbers.
Since there are no primes that divides at least two of given numbers, we conclude that the LCM is a product of starting numbers.
LCM = 49 · 25 · 16 = 19600
This solution can be visualized using a Venn diagram.
