Given numbers are 515,381,825,135
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,381,825,135 is 97126425.
Find LCM of 515,381,825,135 with Prime Factorization
| 3 | 515, 381, 825, 135 |
| 5 | 515, 127, 275, 45 |
| 103, 127, 55, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 103 x 127 x 55 x 9 = 97126425
Therefore, the lowest common multiple of 515,381,825,135 is 97126425.
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.
515 x 381 x 825 x 135 = 21853445625
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.
515 : 1, 5, 103, 515
381 : 1, 3, 127, 381
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
135 : 1, 3, 5, 9, 15, 27, 45, 135
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,381,825,135, is 1.
Now, the common factors can be found like this.
515:5x 103
381:3x 127
825:3x 5x 5x 11
135:3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5 = 225
Therefore, the value for common factors is 225.
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 = 21853445625/(1x225)
LCM = 21853445625/225
LCM = 97126425
Thus, we can understand that the LCM of 515,381,825,135 is 97126425.
