Given numbers are 813,838,429,462
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,838,429,462 is 681975294.
Find LCM of 813,838,429,462 with Prime Factorization
| 2 | 813, 838, 429, 462 |
| 3 | 813, 419, 429, 231 |
| 11 | 271, 419, 143, 77 |
| 271, 419, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 271 x 419 x 13 x 7 = 681975294
Therefore, the lowest common multiple of 813,838,429,462 is 681975294.
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 838 x 429 x 462 = 135031108212
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
838 : 1, 2, 419, 838
429 : 1, 3, 11, 13, 33, 39, 143, 429
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,838,429,462, is 1.
Now, the common factors can be found like this.
813:3x 271
838:2x 419
429:3x 11x 13
462:2x 3x 7x 11
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 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 135031108212/(1x198)
LCM = 135031108212/198
LCM = 681975294
Thus, we can understand that the LCM of 813,838,429,462 is 681975294.
