Given numbers are 923,386,840,515,857
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 923,386,840,515,857 is 13208586441960.
Find LCM of 923,386,840,515,857 with Prime Factorization
| 2 | 923, 386, 840, 515, 857 |
| 5 | 923, 193, 420, 515, 857 |
| 923, 193, 84, 103, 857 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 923 x 193 x 84 x 103 x 857 = 13208586441960
Therefore, the lowest common multiple of 923,386,840,515,857 is 13208586441960.
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.
923 x 386 x 840 x 515 x 857 = 132085864419600
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.
923 : 1, 13, 71, 923
386 : 1, 2, 193, 386
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
515 : 1, 5, 103, 515
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,386,840,515,857, is 1.
Now, the common factors can be found like this.
923:13x 71
386:2x 193
840:2x 2x 2x 3x 5x 7
515:5x 103
857:857
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 132085864419600/(1x10)
LCM = 132085864419600/10
LCM = 13208586441960
Thus, we can understand that the LCM of 923,386,840,515,857 is 13208586441960.
