Given numbers are 555,715,331,840,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 555,715,331,840,247 is 27951083160.
Find LCM of 555,715,331,840,247 with Prime Factorization
| 3 | 555, 715, 331, 840, 247 |
| 5 | 185, 715, 331, 280, 247 |
| 13 | 37, 143, 331, 56, 247 |
| 37, 11, 331, 56, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 37 x 11 x 331 x 56 x 19 = 27951083160
Therefore, the lowest common multiple of 555,715,331,840,247 is 27951083160.
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.
555 x 715 x 331 x 840 x 247 = 27252306081000
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.
555 : 1, 3, 5, 15, 37, 111, 185, 555
715 : 1, 5, 11, 13, 55, 65, 143, 715
331 : 1, 331
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 555,715,331,840,247, is 1.
Now, the common factors can be found like this.
555:3x 5x 37
715:5x 11x 13
331:331
840:2x 2x 2x 3x 5x 7
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 13 = 975
Therefore, the value for common factors is 975.
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 = 27252306081000/(1x975)
LCM = 27252306081000/975
LCM = 27951083160
Thus, we can understand that the LCM of 555,715,331,840,247 is 27951083160.
