Given numbers are 831,258,407,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,258,407,315 is 3054099510.
Find LCM of 831,258,407,315 with Prime Factorization
| 3 | 831, 258, 407, 315 |
| 277, 86, 407, 105 |
Multiply the prime numbers at the bottom and the left side.
3 x 277 x 86 x 407 x 105 = 3054099510
Therefore, the lowest common multiple of 831,258,407,315 is 3054099510.
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.
831 x 258 x 407 x 315 = 27486895590
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.
831 : 1, 3, 277, 831
258 : 1, 2, 3, 6, 43, 86, 129, 258
407 : 1, 11, 37, 407
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,258,407,315, is 1.
Now, the common factors can be found like this.
831:3x 277
258:2x 3x 43
407:11x 37
315:3x 3x 5x 7
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 = 27486895590/(1x9)
LCM = 27486895590/9
LCM = 3054099510
Thus, we can understand that the LCM of 831,258,407,315 is 3054099510.
