Given numbers are 768,618,729,555,534
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 768,618,729,555,534 is 316494708480.
Find LCM of 768,618,729,555,534 with Prime Factorization
| 2 | 768, 618, 729, 555, 534 |
| 3 | 384, 309, 729, 555, 267 |
| 128, 103, 243, 185, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 128 x 103 x 243 x 185 x 89 = 316494708480
Therefore, the lowest common multiple of 768,618,729,555,534 is 316494708480.
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.
768 x 618 x 729 x 555 x 534 = 102544285547520
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.
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
618 : 1, 2, 3, 6, 103, 206, 309, 618
729 : 1, 3, 9, 27, 81, 243, 729
555 : 1, 3, 5, 15, 37, 111, 185, 555
534 : 1, 2, 3, 6, 89, 178, 267, 534
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,618,729,555,534, is 3.
Now, the common factors can be found like this.
768:2x 2x 2x 2x 2x 2x 2x 2x 3
618:2x 3x 103
729:3x 3x 3x 3x 3x 3
555:3x 5x 37
534:2x 3x 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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 102544285547520/(3x108)
LCM = 102544285547520/324
LCM = 316494708480
Thus, we can understand that the LCM of 768,618,729,555,534 is 316494708480.
