Given numbers are 145,687,107,670
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 145,687,107,670 is 1428279870.
Find LCM of 145,687,107,670 with Prime Factorization
| 5 | 145, 687, 107, 670 |
| 29, 687, 107, 134 |
Multiply the prime numbers at the bottom and the left side.
5 x 29 x 687 x 107 x 134 = 1428279870
Therefore, the lowest common multiple of 145,687,107,670 is 1428279870.
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.
145 x 687 x 107 x 670 = 7141399350
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.
145 : 1, 5, 29, 145
687 : 1, 3, 229, 687
107 : 1, 107
670 : 1, 2, 5, 10, 67, 134, 335, 670
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 145,687,107,670, is 1.
Now, the common factors can be found like this.
145:5x 29
687:3x 229
107:107
670:2x 5x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 7141399350/(1x5)
LCM = 7141399350/5
LCM = 1428279870
Thus, we can understand that the LCM of 145,687,107,670 is 1428279870.
