Given numbers are 131,545,437,345,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,545,437,345,915 is 5709529545.
Find LCM of 131,545,437,345,915 with Prime Factorization
| 3 | 131, 545, 437, 345, 915 |
| 5 | 131, 545, 437, 115, 305 |
| 23 | 131, 109, 437, 23, 61 |
| 131, 109, 19, 1, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 131 x 109 x 19 x 1 x 61 = 5709529545
Therefore, the lowest common multiple of 131,545,437,345,915 is 5709529545.
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.
131 x 545 x 437 x 345 x 915 = 9848938465125
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.
131 : 1, 131
545 : 1, 5, 109, 545
437 : 1, 19, 23, 437
345 : 1, 3, 5, 15, 23, 69, 115, 345
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,545,437,345,915, is 1.
Now, the common factors can be found like this.
131:131
545:5x 109
437:19x 23
345:3x 5x 23
915:3x 5x 61
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 5x 23 = 1725
Therefore, the value for common factors is 1725.
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 = 9848938465125/(1x1725)
LCM = 9848938465125/1725
LCM = 5709529545
Thus, we can understand that the LCM of 131,545,437,345,915 is 5709529545.
