Given numbers are 926,840,630,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 926,840,630,815 is 190181880.
Find LCM of 926,840,630,815 with Prime Factorization
| 2 | 926, 840, 630, 815 |
| 3 | 463, 420, 315, 815 |
| 5 | 463, 140, 105, 815 |
| 7 | 463, 28, 21, 163 |
| 463, 4, 3, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 463 x 4 x 3 x 163 = 190181880
Therefore, the lowest common multiple of 926,840,630,815 is 190181880.
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.
926 x 840 x 630 x 815 = 399381948000
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.
926 : 1, 2, 463, 926
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
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 926,840,630,815, is 1.
Now, the common factors can be found like this.
926:2x 463
840:2x 2x 2x 3x 5x 7
630:2x 3x 3x 5x 7
815:5x 163
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 3x 5x 5x 7 = 2100
Therefore, the value for common factors is 2100.
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 = 399381948000/(1x2100)
LCM = 399381948000/2100
LCM = 190181880
Thus, we can understand that the LCM of 926,840,630,815 is 190181880.
