Given numbers are 578,612,605,438,478
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,612,605,438,478 is 109818745740.
Find LCM of 578,612,605,438,478 with Prime Factorization
| 2 | 578, 612, 605, 438, 478 |
| 3 | 289, 306, 605, 219, 239 |
| 17 | 289, 102, 605, 73, 239 |
| 17, 6, 605, 73, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 17 x 6 x 605 x 73 x 239 = 109818745740
Therefore, the lowest common multiple of 578,612,605,438,478 is 109818745740.
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.
578 x 612 x 605 x 438 x 478 = 44806048261920
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.
578 : 1, 2, 17, 34, 289, 578
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
605 : 1, 5, 11, 55, 121, 605
438 : 1, 2, 3, 6, 73, 146, 219, 438
478 : 1, 2, 239, 478
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,612,605,438,478, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
612:2x 2x 3x 3x 17
605:5x 11x 11
438:2x 3x 73
478:2x 239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 17 = 408
Therefore, the value for common factors is 408.
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 = 44806048261920/(1x408)
LCM = 44806048261920/408
LCM = 109818745740
Thus, we can understand that the LCM of 578,612,605,438,478 is 109818745740.
