Given numbers are 605,468,136,578
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,468,136,578 is 163654920.
Find LCM of 605,468,136,578 with Prime Factorization
| 2 | 605, 468, 136, 578 |
| 2 | 605, 234, 68, 289 |
| 17 | 605, 117, 34, 289 |
| 605, 117, 2, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 605 x 117 x 2 x 17 = 163654920
Therefore, the lowest common multiple of 605,468,136,578 is 163654920.
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 468 x 136 x 578 = 22257069120
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
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
136 : 1, 2, 4, 8, 17, 34, 68, 136
578 : 1, 2, 17, 34, 289, 578
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,468,136,578, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
468:2x 2x 3x 3x 13
136:2x 2x 2x 17
578:2x 17x 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 2x 2x 17 = 136
Therefore, the value for common factors is 136.
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 = 22257069120/(1x136)
LCM = 22257069120/136
LCM = 163654920
Thus, we can understand that the LCM of 605,468,136,578 is 163654920.
