Given numbers are 398,492,382,830,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,492,382,830,894 is 1156340965380.
Find LCM of 398,492,382,830,894 with Prime Factorization
| 2 | 398, 492, 382, 830, 894 |
| 3 | 199, 246, 191, 415, 447 |
| 199, 82, 191, 415, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 199 x 82 x 191 x 415 x 149 = 1156340965380
Therefore, the lowest common multiple of 398,492,382,830,894 is 1156340965380.
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 492 x 382 x 830 x 894 = 55504366338240
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
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
382 : 1, 2, 191, 382
830 : 1, 2, 5, 10, 83, 166, 415, 830
894 : 1, 2, 3, 6, 149, 298, 447, 894
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,492,382,830,894, is 2.
Now, the common factors can be found like this.
398:2x 199
492:2x 2x 3x 41
382:2x 191
830:2x 5x 83
894:2x 3x 149
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 3 = 24
Therefore, the value for common factors is 24.
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 = 55504366338240/(2x24)
LCM = 55504366338240/48
LCM = 1156340965380
Thus, we can understand that the LCM of 398,492,382,830,894 is 1156340965380.
