Given numbers are 906,871,384,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 906,871,384,840 is 1767642240.
Find LCM of 906,871,384,840 with Prime Factorization
| 2 | 906, 871, 384, 840 |
| 2 | 453, 871, 192, 420 |
| 2 | 453, 871, 96, 210 |
| 3 | 453, 871, 48, 105 |
| 151, 871, 16, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 151 x 871 x 16 x 35 = 1767642240
Therefore, the lowest common multiple of 906,871,384,840 is 1767642240.
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.
906 x 871 x 384 x 840 = 254540482560
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.
906 : 1, 2, 3, 6, 151, 302, 453, 906
871 : 1, 13, 67, 871
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,871,384,840, is 1.
Now, the common factors can be found like this.
906:2x 3x 151
871:13x 67
384:2x 2x 2x 2x 2x 2x 2x 3
840:2x 2x 2x 3x 5x 7
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 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 254540482560/(1x144)
LCM = 254540482560/144
LCM = 1767642240
Thus, we can understand that the LCM of 906,871,384,840 is 1767642240.
