Given numbers are 858,668,247,331,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,668,247,331,856 is 385681779912.
Find LCM of 858,668,247,331,856 with Prime Factorization
| 2 | 858, 668, 247, 331, 856 |
| 2 | 429, 334, 247, 331, 428 |
| 13 | 429, 167, 247, 331, 214 |
| 33, 167, 19, 331, 214 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 33 x 167 x 19 x 331 x 214 = 385681779912
Therefore, the lowest common multiple of 858,668,247,331,856 is 385681779912.
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.
858 x 668 x 247 x 331 x 856 = 40110905110848
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
668 : 1, 2, 4, 167, 334, 668
247 : 1, 13, 19, 247
331 : 1, 331
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,668,247,331,856, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
668:2x 2x 167
247:13x 19
331:331
856:2x 2x 2x 107
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 13 = 104
Therefore, the value for common factors is 104.
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 = 40110905110848/(1x104)
LCM = 40110905110848/104
LCM = 385681779912
Thus, we can understand that the LCM of 858,668,247,331,856 is 385681779912.
