Given numbers are 398,603,309,351
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,603,309,351 is 964055898.
Find LCM of 398,603,309,351 with Prime Factorization
| 3 | 398, 603, 309, 351 |
| 3 | 398, 201, 103, 117 |
| 398, 67, 103, 39 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 398 x 67 x 103 x 39 = 964055898
Therefore, the lowest common multiple of 398,603,309,351 is 964055898.
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 603 x 309 x 351 = 26029509246
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
603 : 1, 3, 9, 67, 201, 603
309 : 1, 3, 103, 309
351 : 1, 3, 9, 13, 27, 39, 117, 351
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,603,309,351, is 1.
Now, the common factors can be found like this.
398:2x 199
603:3x 3x 67
309:3x 103
351:3x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3 = 27
Therefore, the value for common factors is 27.
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 = 26029509246/(1x27)
LCM = 26029509246/27
LCM = 964055898
Thus, we can understand that the LCM of 398,603,309,351 is 964055898.
