Given numbers are 836,128,458,684,892
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 836,128,458,684,892 is 12295299456.
Find LCM of 836,128,458,684,892 with Prime Factorization
| 2 | 836, 128, 458, 684, 892 |
| 2 | 418, 64, 229, 342, 446 |
| 19 | 209, 32, 229, 171, 223 |
| 11, 32, 229, 9, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 11 x 32 x 229 x 9 x 223 = 12295299456
Therefore, the lowest common multiple of 836,128,458,684,892 is 12295299456.
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.
836 x 128 x 458 x 684 x 892 = 29902168276992
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.
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
128 : 1, 2, 4, 8, 16, 32, 64, 128
458 : 1, 2, 229, 458
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
892 : 1, 2, 4, 223, 446, 892
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,128,458,684,892, is 2.
Now, the common factors can be found like this.
836:2x 2x 11x 19
128:2x 2x 2x 2x 2x 2x 2
458:2x 229
684:2x 2x 3x 3x 19
892:2x 2x 223
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 2x 2x 2x 19 = 1216
Therefore, the value for common factors is 1216.
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 = 29902168276992/(2x1216)
LCM = 29902168276992/2432
LCM = 12295299456
Thus, we can understand that the LCM of 836,128,458,684,892 is 12295299456.
