Find LCM of 612,387,221,832 with Prime Factorization
| 2 | 612, 387, 221, 832 |
| 2 | 306, 387, 221, 416 |
| 3 | 153, 387, 221, 208 |
| 3 | 51, 129, 221, 208 |
| 13 | 17, 43, 221, 208 |
| 17 | 17, 43, 17, 16 |
| 1, 43, 1, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 13 x 17 x 1 x 43 x 1 x 16 = 5473728
Therefore, the lowest common multiple of 612,387,221,832 is 5473728.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
612 x 387 x 221 x 832 = 43548979968
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
387 : 1, 3, 9, 43, 129, 387
221 : 1, 13, 17, 221
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,387,221,832, is 1.
Now, the common factors can be found like this.
612:2x 2x 3x 3x 17
387:3x 3x 43
221:13x 17
832:2x 2x 2x 2x 2x 2x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 13x 17 = 7956
Therefore, the value for common factors is 7956.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 43548979968/(1x7956)
LCM = 43548979968/7956
LCM = 5473728
Thus, we can understand that the LCM of 612,387,221,832 is 5473728.
