Given numbers are 387,208,673,430,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 387,208,673,430,380 is 5146511760.
Find LCM of 387,208,673,430,380 with Prime Factorization
| 2 | 387, 208, 673, 430, 380 |
| 2 | 387, 104, 673, 215, 190 |
| 5 | 387, 52, 673, 215, 95 |
| 43 | 387, 52, 673, 43, 19 |
| 9, 52, 673, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 9 x 52 x 673 x 1 x 19 = 5146511760
Therefore, the lowest common multiple of 387,208,673,430,380 is 5146511760.
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.
387 x 208 x 673 x 430 x 380 = 8852000227200
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.
387 : 1, 3, 9, 43, 129, 387
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
673 : 1, 673
430 : 1, 2, 5, 10, 43, 86, 215, 430
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,208,673,430,380, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
208:2x 2x 2x 2x 13
673:673
430:2x 5x 43
380:2x 2x 5x 19
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 5x 43 = 1720
Therefore, the value for common factors is 1720.
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 = 8852000227200/(1x1720)
LCM = 8852000227200/1720
LCM = 5146511760
Thus, we can understand that the LCM of 387,208,673,430,380 is 5146511760.
