Given numbers are 368,561,326,836,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 368,561,326,836,428 is 68412531792.
Find LCM of 368,561,326,836,428 with Prime Factorization
| 2 | 368, 561, 326, 836, 428 |
| 2 | 184, 561, 163, 418, 214 |
| 11 | 92, 561, 163, 209, 107 |
| 92, 51, 163, 19, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 92 x 51 x 163 x 19 x 107 = 68412531792
Therefore, the lowest common multiple of 368,561,326,836,428 is 68412531792.
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.
368 x 561 x 326 x 836 x 428 = 24081211190784
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.
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
561 : 1, 3, 11, 17, 33, 51, 187, 561
326 : 1, 2, 163, 326
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 368,561,326,836,428, is 1.
Now, the common factors can be found like this.
368:2x 2x 2x 2x 23
561:3x 11x 17
326:2x 163
836:2x 2x 11x 19
428:2x 2x 107
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 11 = 352
Therefore, the value for common factors is 352.
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 = 24081211190784/(1x352)
LCM = 24081211190784/352
LCM = 68412531792
Thus, we can understand that the LCM of 368,561,326,836,428 is 68412531792.
