Given numbers are 382,544,605,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 382,544,605,715 is 817204960.
Find LCM of 382,544,605,715 with Prime Factorization
| 2 | 382, 544, 605, 715 |
| 5 | 191, 272, 605, 715 |
| 11 | 191, 272, 121, 143 |
| 191, 272, 11, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 191 x 272 x 11 x 13 = 817204960
Therefore, the lowest common multiple of 382,544,605,715 is 817204960.
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.
382 x 544 x 605 x 715 = 89892545600
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.
382 : 1, 2, 191, 382
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
605 : 1, 5, 11, 55, 121, 605
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,544,605,715, is 1.
Now, the common factors can be found like this.
382:2x 191
544:2x 2x 2x 2x 2x 17
605:5x 11x 11
715:5x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 89892545600/(1x110)
LCM = 89892545600/110
LCM = 817204960
Thus, we can understand that the LCM of 382,544,605,715 is 817204960.
