Given numbers are 858,786,625,578
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,786,625,578 is 20301888750.
Find LCM of 858,786,625,578 with Prime Factorization
| 2 | 858, 786, 625, 578 |
| 3 | 429, 393, 625, 289 |
| 143, 131, 625, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 143 x 131 x 625 x 289 = 20301888750
Therefore, the lowest common multiple of 858,786,625,578 is 20301888750.
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 786 x 625 x 578 = 243622665000
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
786 : 1, 2, 3, 6, 131, 262, 393, 786
625 : 1, 5, 25, 125, 625
578 : 1, 2, 17, 34, 289, 578
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,786,625,578, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
786:2x 3x 131
625:5x 5x 5x 5
578:2x 17x 17
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 3 = 12
Therefore, the value for common factors is 12.
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 = 243622665000/(1x12)
LCM = 243622665000/12
LCM = 20301888750
Thus, we can understand that the LCM of 858,786,625,578 is 20301888750.
