Given numbers are 417,299,639,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 417,299,639,987 is 8737410591.
Find LCM of 417,299,639,987 with Prime Factorization
| 3 | 417, 299, 639, 987 |
| 139, 299, 213, 329 |
Multiply the prime numbers at the bottom and the left side.
3 x 139 x 299 x 213 x 329 = 8737410591
Therefore, the lowest common multiple of 417,299,639,987 is 8737410591.
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.
417 x 299 x 639 x 987 = 78636695319
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.
417 : 1, 3, 139, 417
299 : 1, 13, 23, 299
639 : 1, 3, 9, 71, 213, 639
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,299,639,987, is 1.
Now, the common factors can be found like this.
417:3x 139
299:13x 23
639:3x 3x 71
987:3x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 78636695319/(1x9)
LCM = 78636695319/9
LCM = 8737410591
Thus, we can understand that the LCM of 417,299,639,987 is 8737410591.
