Given numbers are 543,538,408
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 543,538,408 is 19865112.
Find LCM of 543,538,408 with Prime Factorization
| 2 | 543, 538, 408 |
| 3 | 543, 269, 204 |
| 181, 269, 68 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 181 x 269 x 68 = 19865112
Therefore, the lowest common multiple of 543,538,408 is 19865112.
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 538 x 408 = 119190672
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
538 : 1, 2, 269, 538
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,538,408, is 1.
Now, the common factors can be found like this.
543:3x 181
538:2x 269
408:2x 2x 2x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 119190672/(1x6)
LCM = 119190672/6
LCM = 19865112
Thus, we can understand that the LCM of 543,538,408 is 19865112.
