Given numbers are 543,561,731,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 543,561,731,870 is 1266216270.
Find LCM of 543,561,731,870 with Prime Factorization
| 3 | 543, 561, 731, 870 |
| 17 | 181, 187, 731, 290 |
| 181, 11, 43, 290 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 181 x 11 x 43 x 290 = 1266216270
Therefore, the lowest common multiple of 543,561,731,870 is 1266216270.
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.
543 x 561 x 731 x 870 = 193731089310
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.
543 : 1, 3, 181, 543
561 : 1, 3, 11, 17, 33, 51, 187, 561
731 : 1, 17, 43, 731
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,561,731,870, is 1.
Now, the common factors can be found like this.
543:3x 181
561:3x 11x 17
731:17x 43
870:2x 3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 17 = 153
Therefore, the value for common factors is 153.
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 = 193731089310/(1x153)
LCM = 193731089310/153
LCM = 1266216270
Thus, we can understand that the LCM of 543,561,731,870 is 1266216270.
