Given numbers are 382,574,656,668
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 382,574,656,668 is 146471024.
Find LCM of 382,574,656,668 with Prime Factorization
| 2 | 382, 574, 656, 668 |
| 2 | 191, 287, 328, 334 |
| 41 | 191, 287, 164, 167 |
| 191, 7, 4, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 41 x 191 x 7 x 4 x 167 = 146471024
Therefore, the lowest common multiple of 382,574,656,668 is 146471024.
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.
382 x 574 x 656 x 668 = 96084991744
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.
382 : 1, 2, 191, 382
574 : 1, 2, 7, 14, 41, 82, 287, 574
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
668 : 1, 2, 4, 167, 334, 668
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,574,656,668, is 2.
Now, the common factors can be found like this.
382:2x 191
574:2x 7x 41
656:2x 2x 2x 2x 41
668:2x 2x 167
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 41 = 328
Therefore, the value for common factors is 328.
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 = 96084991744/(2x328)
LCM = 96084991744/656
LCM = 146471024
Thus, we can understand that the LCM of 382,574,656,668 is 146471024.
