The LCM of 408,715,986,384 is 135358080.
Find LCM of 408,715,986,384 with Prime Factorization
| 2 | 408, 715, 986, 384 |
| 2 | 204, 715, 493, 192 |
| 2 | 102, 715, 493, 96 |
| 3 | 51, 715, 493, 48 |
| 17 | 17, 715, 493, 16 |
| 1, 715, 29, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 17 x 1 x 715 x 29 x 16 = 135358080
Therefore, the lowest common multiple of 408,715,986,384 is 135358080.
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 715 x 986 x 384 = 110452193280
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
715 : 1, 5, 11, 13, 55, 65, 143, 715
986 : 1, 2, 17, 29, 34, 58, 493, 986
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,715,986,384, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
715:5x 11x 13
986:2x 17x 29
384:2x 2x 2x 2x 2x 2x 2x 3
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 17 = 816
Therefore, the value for common factors is 816.
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 = 110452193280/(1x816)
LCM = 110452193280/816
LCM = 135358080
Thus, we can understand that the LCM of 408,715,986,384 is 135358080.
