Given numbers are 578,204,197,913,478
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,204,197,913,478 is 149078149572.
Find LCM of 578,204,197,913,478 with Prime Factorization
| 2 | 578, 204, 197, 913, 478 |
| 17 | 289, 102, 197, 913, 239 |
| 17, 6, 197, 913, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 17 x 6 x 197 x 913 x 239 = 149078149572
Therefore, the lowest common multiple of 578,204,197,913,478 is 149078149572.
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 204 x 197 x 913 x 478 = 10137314170896
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
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
197 : 1, 197
913 : 1, 11, 83, 913
478 : 1, 2, 239, 478
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,204,197,913,478, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
204:2x 2x 3x 17
197:197
913:11x 83
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 17 = 68
Therefore, the value for common factors is 68.
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 = 10137314170896/(1x68)
LCM = 10137314170896/68
LCM = 149078149572
Thus, we can understand that the LCM of 578,204,197,913,478 is 149078149572.
