Find LCM of 368,421,363,687,528 with Prime Factorization
| 2 | 368, 421, 363, 687, 528 |
| 2 | 184, 421, 363, 687, 264 |
| 2 | 92, 421, 363, 687, 132 |
| 2 | 46, 421, 363, 687, 66 |
| 3 | 23, 421, 363, 687, 33 |
| 11 | 23, 421, 121, 229, 11 |
| 23, 421, 1, 229, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 11 x 23 x 421 x 1 x 229 x 11 = 12878699856
Therefore, the lowest common multiple of 368,421,363,687,528 is 12878699856.
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.
368 x 421 x 363 x 687 x 528 = 20399860571904
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.
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
421 : 1, 421
363 : 1, 3, 11, 33, 121, 363
687 : 1, 3, 229, 687
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 368,421,363,687,528, is 1.
Now, the common factors can be found like this.
368:2x 2x 2x 2x 23
421:421
363:3x 11x 11
687:3x 229
528:2x 2x 2x 2x 3x 11
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 2x 2x 3x 3x 11 = 1584
Therefore, the value for common factors is 1584.
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 = 20399860571904/(1x1584)
LCM = 20399860571904/1584
LCM = 12878699856
Thus, we can understand that the LCM of 368,421,363,687,528 is 12878699856.
