Given numbers are 508,845,451,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 508,845,451,840 is 8131042920.
Find LCM of 508,845,451,840 with Prime Factorization
| 2 | 508, 845, 451, 840 |
| 2 | 254, 845, 451, 420 |
| 5 | 127, 845, 451, 210 |
| 127, 169, 451, 42 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 127 x 169 x 451 x 42 = 8131042920
Therefore, the lowest common multiple of 508,845,451,840 is 8131042920.
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.
508 x 845 x 451 x 840 = 162620858400
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.
508 : 1, 2, 4, 127, 254, 508
845 : 1, 5, 13, 65, 169, 845
451 : 1, 11, 41, 451
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 508,845,451,840, is 1.
Now, the common factors can be found like this.
508:2x 2x 127
845:5x 13x 13
451:11x 41
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 5 = 20
Therefore, the value for common factors is 20.
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 = 162620858400/(1x20)
LCM = 162620858400/20
LCM = 8131042920
Thus, we can understand that the LCM of 508,845,451,840 is 8131042920.
