Given numbers are 579,729,543,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 579,729,543,840 is 7130523960.
Find LCM of 579,729,543,840 with Prime Factorization
| 3 | 579, 729, 543, 840 |
| 193, 243, 181, 280 |
Multiply the prime numbers at the bottom and the left side.
3 x 193 x 243 x 181 x 280 = 7130523960
Therefore, the lowest common multiple of 579,729,543,840 is 7130523960.
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.
579 x 729 x 543 x 840 = 192524146920
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.
579 : 1, 3, 193, 579
729 : 1, 3, 9, 27, 81, 243, 729
543 : 1, 3, 181, 543
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
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 579,729,543,840, is 3.
Now, the common factors can be found like this.
579:3x 193
729:3x 3x 3x 3x 3x 3
543:3x 181
840:2x 2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 192524146920/(3x9)
LCM = 192524146920/27
LCM = 7130523960
Thus, we can understand that the LCM of 579,729,543,840 is 7130523960.
