Given numbers are 813,513,521,836,310
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,513,521,836,310 is 493979304060.
Find LCM of 813,513,521,836,310 with Prime Factorization
| 2 | 813, 513, 521, 836, 310 |
| 3 | 813, 513, 521, 418, 155 |
| 19 | 271, 171, 521, 418, 155 |
| 271, 9, 521, 22, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 271 x 9 x 521 x 22 x 155 = 493979304060
Therefore, the lowest common multiple of 813,513,521,836,310 is 493979304060.
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.
813 x 513 x 521 x 836 x 310 = 56313640662840
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.
813 : 1, 3, 271, 813
513 : 1, 3, 9, 19, 27, 57, 171, 513
521 : 1, 521
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
310 : 1, 2, 5, 10, 31, 62, 155, 310
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,513,521,836,310, is 1.
Now, the common factors can be found like this.
813:3x 271
513:3x 3x 3x 19
521:521
836:2x 2x 11x 19
310:2x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 19 = 114
Therefore, the value for common factors is 114.
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 = 56313640662840/(1x114)
LCM = 56313640662840/114
LCM = 493979304060
Thus, we can understand that the LCM of 813,513,521,836,310 is 493979304060.
