Question

Find the LCM of 100,525,650 using short division method​

Answer 1

Answer:

Step 1) First we find and list the prime factors of 3, 13, and 33 (Prime Factorization):

Prime Factors of 3:

3

Prime Factors of 13:

13

Prime Factors of 33:

3, 11

Step 2) Then we look at the frequency of the prime factors as they appear in each set above. List each prime factor the greatest number of times it occurs in any of the sets:

3, 11, 13

Step 3) Finally, we multiply the prime numbers from Step 2 together.

3 x 11 x 13 = 429

That's it. The Least Common Multiple (LCM) of 3, 13, and 33 is 429.
