Given numbers are 398,468,752,331
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,468,752,331 is 5795418096.
Find LCM of 398,468,752,331 with Prime Factorization
| 2 | 398, 468, 752, 331 |
| 2 | 199, 234, 376, 331 |
| 199, 117, 188, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 199 x 117 x 188 x 331 = 5795418096
Therefore, the lowest common multiple of 398,468,752,331 is 5795418096.
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.
398 x 468 x 752 x 331 = 46363344768
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.
398 : 1, 2, 199, 398
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
331 : 1, 331
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,468,752,331, is 1.
Now, the common factors can be found like this.
398:2x 199
468:2x 2x 3x 3x 13
752:2x 2x 2x 2x 47
331:331
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 2 = 8
Therefore, the value for common factors is 8.
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 = 46363344768/(1x8)
LCM = 46363344768/8
LCM = 5795418096
Thus, we can understand that the LCM of 398,468,752,331 is 5795418096.
