The LCM of 408,381,918,586 is 136638792.
Find LCM of 408,381,918,586 with Prime Factorization
| 2 | 408, 381, 918, 586 |
| 3 | 204, 381, 459, 293 |
| 17 | 68, 127, 153, 293 |
| 4, 127, 9, 293 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 4 x 127 x 9 x 293 = 136638792
Therefore, the lowest common multiple of 408,381,918,586 is 136638792.
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.
408 x 381 x 918 x 586 = 83622940704
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
381 : 1, 3, 127, 381
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
586 : 1, 2, 293, 586
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,381,918,586, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
381:3x 127
918:2x 3x 3x 3x 17
586:2x 293
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 3x 17 = 612
Therefore, the value for common factors is 612.
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 = 83622940704/(1x612)
LCM = 83622940704/612
LCM = 136638792
Thus, we can understand that the LCM of 408,381,918,586 is 136638792.
