Given numbers are 386,818,388,712
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 386,818,388,712 is 5451704968.
Find LCM of 386,818,388,712 with Prime Factorization
| 2 | 386, 818, 388, 712 |
| 2 | 193, 409, 194, 356 |
| 193, 409, 97, 178 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 193 x 409 x 97 x 178 = 5451704968
Therefore, the lowest common multiple of 386,818,388,712 is 5451704968.
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.
386 x 818 x 388 x 712 = 87227279488
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.
386 : 1, 2, 193, 386
818 : 1, 2, 409, 818
388 : 1, 2, 4, 97, 194, 388
712 : 1, 2, 4, 8, 89, 178, 356, 712
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,818,388,712, is 2.
Now, the common factors can be found like this.
386:2x 193
818:2x 409
388:2x 2x 97
712:2x 2x 2x 89
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 2 = 8
Therefore, the value for common factors is 8.
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 = 87227279488/(2x8)
LCM = 87227279488/16
LCM = 5451704968
Thus, we can understand that the LCM of 386,818,388,712 is 5451704968.
