Given numbers are 643,704,478,764,330
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,704,478,764,330 is 309960361920.
Find LCM of 643,704,478,764,330 with Prime Factorization
| 2 | 643, 704, 478, 764, 330 |
| 2 | 643, 352, 239, 382, 165 |
| 11 | 643, 176, 239, 191, 165 |
| 643, 16, 239, 191, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 643 x 16 x 239 x 191 x 15 = 309960361920
Therefore, the lowest common multiple of 643,704,478,764,330 is 309960361920.
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.
643 x 704 x 478 x 764 x 330 = 54553023697920
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.
643 : 1, 643
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
478 : 1, 2, 239, 478
764 : 1, 2, 4, 191, 382, 764
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,704,478,764,330, is 1.
Now, the common factors can be found like this.
643:643
704:2x 2x 2x 2x 2x 2x 11
478:2x 239
764:2x 2x 191
330:2x 3x 5x 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 11 = 176
Therefore, the value for common factors is 176.
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 = 54553023697920/(1x176)
LCM = 54553023697920/176
LCM = 309960361920
Thus, we can understand that the LCM of 643,704,478,764,330 is 309960361920.
