Given numbers are 639,818,932,568,179
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,818,932,568,179 is 87201329256.
Find LCM of 639,818,932,568,179 with Prime Factorization
| 2 | 639, 818, 932, 568, 179 |
| 2 | 639, 409, 466, 284, 179 |
| 71 | 639, 409, 233, 142, 179 |
| 9, 409, 233, 2, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 71 x 9 x 409 x 233 x 2 x 179 = 87201329256
Therefore, the lowest common multiple of 639,818,932,568,179 is 87201329256.
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.
639 x 818 x 932 x 568 x 179 = 49530355017408
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.
639 : 1, 3, 9, 71, 213, 639
818 : 1, 2, 409, 818
932 : 1, 2, 4, 233, 466, 932
568 : 1, 2, 4, 8, 71, 142, 284, 568
179 : 1, 179
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,818,932,568,179, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
818:2x 409
932:2x 2x 233
568:2x 2x 2x 71
179:179
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 71 = 568
Therefore, the value for common factors is 568.
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 = 49530355017408/(1x568)
LCM = 49530355017408/568
LCM = 87201329256
Thus, we can understand that the LCM of 639,818,932,568,179 is 87201329256.
