Given numbers are 619,418,420,217,543
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,418,420,217,543 is 304878286020.
Find LCM of 619,418,420,217,543 with Prime Factorization
| 2 | 619, 418, 420, 217, 543 |
| 3 | 619, 209, 210, 217, 543 |
| 7 | 619, 209, 70, 217, 181 |
| 619, 209, 10, 31, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 619 x 209 x 10 x 31 x 181 = 304878286020
Therefore, the lowest common multiple of 619,418,420,217,543 is 304878286020.
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.
619 x 418 x 420 x 217 x 543 = 12804888012840
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.
619 : 1, 619
418 : 1, 2, 11, 19, 22, 38, 209, 418
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
217 : 1, 7, 31, 217
543 : 1, 3, 181, 543
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,418,420,217,543, is 1.
Now, the common factors can be found like this.
619:619
418:2x 11x 19
420:2x 2x 3x 5x 7
217:7x 31
543:3x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 12804888012840/(1x42)
LCM = 12804888012840/42
LCM = 304878286020
Thus, we can understand that the LCM of 619,418,420,217,543 is 304878286020.
