Given numbers are 578,537,458,128,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,537,458,128,687 is 4549017216.
Find LCM of 578,537,458,128,687 with Prime Factorization
| 2 | 578, 537, 458, 128, 687 |
| 3 | 289, 537, 229, 64, 687 |
| 229 | 289, 179, 229, 64, 229 |
| 289, 179, 1, 64, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 229 x 289 x 179 x 1 x 64 x 1 = 4549017216
Therefore, the lowest common multiple of 578,537,458,128,687 is 4549017216.
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 537 x 458 x 128 x 687 = 12500699309568
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
537 : 1, 3, 179, 537
458 : 1, 2, 229, 458
128 : 1, 2, 4, 8, 16, 32, 64, 128
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,537,458,128,687, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
537:3x 179
458:2x 229
128:2x 2x 2x 2x 2x 2x 2
687:3x 229
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 3x 229 = 2748
Therefore, the value for common factors is 2748.
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 = 12500699309568/(1x2748)
LCM = 12500699309568/2748
LCM = 4549017216
Thus, we can understand that the LCM of 578,537,458,128,687 is 4549017216.
