Given numbers are 578,616,663,328
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,616,663,328 is 284660376.
Find LCM of 578,616,663,328 with Prime Factorization
| 2 | 578, 616, 663, 328 |
| 2 | 289, 308, 663, 164 |
| 2 | 289, 154, 663, 82 |
| 17 | 289, 77, 663, 41 |
| 17, 77, 39, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 17 x 77 x 39 x 41 = 284660376
Therefore, the lowest common multiple of 578,616,663,328 is 284660376.
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 616 x 663 x 328 = 77427622272
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
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
663 : 1, 3, 13, 17, 39, 51, 221, 663
328 : 1, 2, 4, 8, 41, 82, 164, 328
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,616,663,328, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
616:2x 2x 2x 7x 11
663:3x 13x 17
328:2x 2x 2x 41
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 2x 17 = 272
Therefore, the value for common factors is 272.
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 = 77427622272/(1x272)
LCM = 77427622272/272
LCM = 284660376
Thus, we can understand that the LCM of 578,616,663,328 is 284660376.
