Find LCM of 764,468,391,621,381 with Prime Factorization
| 2 | 764, 468, 391, 621, 381 |
| 2 | 382, 234, 391, 621, 381 |
| 3 | 191, 117, 391, 621, 381 |
| 3 | 191, 39, 391, 207, 127 |
| 23 | 191, 13, 391, 69, 127 |
| 191, 13, 17, 3, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 23 x 191 x 13 x 17 x 3 x 127 = 13316219748
Therefore, the lowest common multiple of 764,468,391,621,381 is 13316219748.
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.
764 x 468 x 391 x 621 x 381 = 33077489854032
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.
764 : 1, 2, 4, 191, 382, 764
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
391 : 1, 17, 23, 391
621 : 1, 3, 9, 23, 27, 69, 207, 621
381 : 1, 3, 127, 381
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 764,468,391,621,381, is 1.
Now, the common factors can be found like this.
764:2x 2x 191
468:2x 2x 3x 3x 13
391:17x 23
621:3x 3x 3x 23
381:3x 127
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 3x 23 = 2484
Therefore, the value for common factors is 2484.
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 = 33077489854032/(1x2484)
LCM = 33077489854032/2484
LCM = 13316219748
Thus, we can understand that the LCM of 764,468,391,621,381 is 13316219748.
