Given numbers are 108,284,364,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 108,284,364,434 is 21631428.
Find LCM of 108,284,364,434 with Prime Factorization
| 2 | 108, 284, 364, 434 |
| 2 | 54, 142, 182, 217 |
| 7 | 27, 71, 91, 217 |
| 27, 71, 13, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 27 x 71 x 13 x 31 = 21631428
Therefore, the lowest common multiple of 108,284,364,434 is 21631428.
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.
108 x 284 x 364 x 434 = 4845439872
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.
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
284 : 1, 2, 4, 71, 142, 284
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
434 : 1, 2, 7, 14, 31, 62, 217, 434
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 108,284,364,434, is 2.
Now, the common factors can be found like this.
108:2x 2x 3x 3x 3
284:2x 2x 71
364:2x 2x 7x 13
434:2x 7x 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 2x 2x 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 4845439872/(2x112)
LCM = 4845439872/224
LCM = 21631428
Thus, we can understand that the LCM of 108,284,364,434 is 21631428.
