Find LCM of 878,846,987,342 with Prime Factorization
| 2 | 878, 846, 987, 342 |
| 3 | 439, 423, 987, 171 |
| 3 | 439, 141, 329, 57 |
| 47 | 439, 47, 329, 19 |
| 439, 1, 7, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 47 x 439 x 1 x 7 x 19 = 49395402
Therefore, the lowest common multiple of 878,846,987,342 is 49395402.
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.
878 x 846 x 987 x 342 = 250731060552
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.
878 : 1, 2, 439, 878
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
987 : 1, 3, 7, 21, 47, 141, 329, 987
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,846,987,342, is 1.
Now, the common factors can be found like this.
878:2x 439
846:2x 3x 3x 47
987:3x 7x 47
342:2x 3x 3x 19
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 3x 3x 3x 47 = 5076
Therefore, the value for common factors is 5076.
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 = 250731060552/(1x5076)
LCM = 250731060552/5076
LCM = 49395402
Thus, we can understand that the LCM of 878,846,987,342 is 49395402.
