Given numbers are 818,506,407,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 818,506,407,920 is 153145960.
Find LCM of 818,506,407,920 with Prime Factorization
| 2 | 818, 506, 407, 920 |
| 11 | 409, 253, 407, 460 |
| 23 | 409, 23, 37, 460 |
| 409, 1, 37, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 23 x 409 x 1 x 37 x 20 = 153145960
Therefore, the lowest common multiple of 818,506,407,920 is 153145960.
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.
818 x 506 x 407 x 920 = 154983711520
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.
818 : 1, 2, 409, 818
506 : 1, 2, 11, 22, 23, 46, 253, 506
407 : 1, 11, 37, 407
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,506,407,920, is 1.
Now, the common factors can be found like this.
818:2x 409
506:2x 11x 23
407:11x 37
920:2x 2x 2x 5x 23
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 11x 23 = 1012
Therefore, the value for common factors is 1012.
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 = 154983711520/(1x1012)
LCM = 154983711520/1012
LCM = 153145960
Thus, we can understand that the LCM of 818,506,407,920 is 153145960.
