Given numbers are 660,487,678,906,808
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 660,487,678,906,808 is 1107846670920.
Find LCM of 660,487,678,906,808 with Prime Factorization
| 2 | 660, 487, 678, 906, 808 |
| 2 | 330, 487, 339, 453, 404 |
| 3 | 165, 487, 339, 453, 202 |
| 55, 487, 113, 151, 202 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 55 x 487 x 113 x 151 x 202 = 1107846670920
Therefore, the lowest common multiple of 660,487,678,906,808 is 1107846670920.
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.
660 x 487 x 678 x 906 x 808 = 159529920612480
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.
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
487 : 1, 487
678 : 1, 2, 3, 6, 113, 226, 339, 678
906 : 1, 2, 3, 6, 151, 302, 453, 906
808 : 1, 2, 4, 8, 101, 202, 404, 808
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,487,678,906,808, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
487:487
678:2x 3x 113
906:2x 3x 151
808:2x 2x 2x 101
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 = 159529920612480/(1x144)
LCM = 159529920612480/144
LCM = 1107846670920
Thus, we can understand that the LCM of 660,487,678,906,808 is 1107846670920.
