Find LCM of 408,781,352,111,284 with Prime Factorization
| 2 | 408, 781, 352, 111, 284 |
| 2 | 204, 781, 176, 111, 142 |
| 2 | 102, 781, 88, 111, 71 |
| 3 | 51, 781, 44, 111, 71 |
| 11 | 17, 781, 44, 37, 71 |
| 71 | 17, 71, 4, 37, 71 |
| 17, 1, 4, 37, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 71 x 17 x 1 x 4 x 37 x 1 = 47159904
Therefore, the lowest common multiple of 408,781,352,111,284 is 47159904.
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.
408 x 781 x 352 x 111 x 284 = 3535860962304
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
781 : 1, 11, 71, 781
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
111 : 1, 3, 37, 111
284 : 1, 2, 4, 71, 142, 284
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,781,352,111,284, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
781:11x 71
352:2x 2x 2x 2x 2x 11
111:3x 37
284:2x 2x 71
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 3x 11x 71 = 74976
Therefore, the value for common factors is 74976.
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 = 3535860962304/(1x74976)
LCM = 3535860962304/74976
LCM = 47159904
Thus, we can understand that the LCM of 408,781,352,111,284 is 47159904.
