Given numbers are 386,627,605,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 386,627,605,686 is 4565745030.
Find LCM of 386,627,605,686 with Prime Factorization
| 2 | 386, 627, 605, 686 |
| 11 | 193, 627, 605, 343 |
| 193, 57, 55, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 193 x 57 x 55 x 343 = 4565745030
Therefore, the lowest common multiple of 386,627,605,686 is 4565745030.
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 627 x 605 x 686 = 100446390660
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
627 : 1, 3, 11, 19, 33, 57, 209, 627
605 : 1, 5, 11, 55, 121, 605
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,627,605,686, is 1.
Now, the common factors can be found like this.
386:2x 193
627:3x 11x 19
605:5x 11x 11
686:2x 7x 7x 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 11 = 22
Therefore, the value for common factors is 22.
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 = 100446390660/(1x22)
LCM = 100446390660/22
LCM = 4565745030
Thus, we can understand that the LCM of 386,627,605,686 is 4565745030.
