Given numbers are 605,418,546,581
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,418,546,581 is 520930410.
Find LCM of 605,418,546,581 with Prime Factorization
| 2 | 605, 418, 546, 581 |
| 7 | 605, 209, 273, 581 |
| 11 | 605, 209, 39, 83 |
| 55, 19, 39, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 55 x 19 x 39 x 83 = 520930410
Therefore, the lowest common multiple of 605,418,546,581 is 520930410.
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.
605 x 418 x 546 x 581 = 80223283140
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.
605 : 1, 5, 11, 55, 121, 605
418 : 1, 2, 11, 19, 22, 38, 209, 418
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
581 : 1, 7, 83, 581
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,418,546,581, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
418:2x 11x 19
546:2x 3x 7x 13
581:7x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11 = 154
Therefore, the value for common factors is 154.
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 = 80223283140/(1x154)
LCM = 80223283140/154
LCM = 520930410
Thus, we can understand that the LCM of 605,418,546,581 is 520930410.
