Given numbers are 831,808,249,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,808,249,380 is 5294367480.
Find LCM of 831,808,249,380 with Prime Factorization
| 2 | 831, 808, 249, 380 |
| 2 | 831, 404, 249, 190 |
| 3 | 831, 202, 249, 95 |
| 277, 202, 83, 95 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 277 x 202 x 83 x 95 = 5294367480
Therefore, the lowest common multiple of 831,808,249,380 is 5294367480.
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 808 x 249 x 380 = 63532409760
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
808 : 1, 2, 4, 8, 101, 202, 404, 808
249 : 1, 3, 83, 249
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,808,249,380, is 1.
Now, the common factors can be found like this.
831:3x 277
808:2x 2x 2x 101
249:3x 83
380:2x 2x 5x 19
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 3 = 12
Therefore, the value for common factors is 12.
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 = 63532409760/(1x12)
LCM = 63532409760/12
LCM = 5294367480
Thus, we can understand that the LCM of 831,808,249,380 is 5294367480.
