What Is The LCM of 35 14 and 21?

Answer 1

First we will find LCM for first two numbers (28 and 35).

Step 1: Find the GCD (Greatest Common Divisor) of 28 and 35 which is 7.

Step 2: Multiply the numbers 28 and 35 together (28 * 35 = 980)

Step 3: Divide the 980 with 7. (980/7 = 140)

So, the LCM of 28 and 35 is 140.

Now we will find the LCM of above result (140) and third number (21) using the same procedure.

The LCM of 28, 35 and 21 is 420.
