Given numbers are 145,377,870,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 145,377,870,687 is 2589990.
Find LCM of 145,377,870,687 with Prime Factorization
| 3 | 145, 377, 870, 687 |
| 5 | 145, 377, 290, 229 |
| 29 | 29, 377, 58, 229 |
| 1, 13, 2, 229 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 29 x 1 x 13 x 2 x 229 = 2589990
Therefore, the lowest common multiple of 145,377,870,687 is 2589990.
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 377 x 870 x 687 = 32672723850
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
377 : 1, 13, 29, 377
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 145,377,870,687, is 1.
Now, the common factors can be found like this.
145:5x 29
377:13x 29
870:2x 3x 5x 29
687:3x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 29x 29 = 12615
Therefore, the value for common factors is 12615.
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 = 32672723850/(1x12615)
LCM = 32672723850/12615
LCM = 2589990
Thus, we can understand that the LCM of 145,377,870,687 is 2589990.
