The LCM of 142,168,378,908,687 is 5580479016.
Find LCM of 142,168,378,908,687 with Prime Factorization
| 2 | 142, 168, 378, 908, 687 |
| 2 | 71, 84, 189, 454, 687 |
| 3 | 71, 42, 189, 227, 687 |
| 7 | 71, 14, 63, 227, 229 |
| 71, 2, 9, 227, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 71 x 2 x 9 x 227 x 229 = 5580479016
Therefore, the lowest common multiple of 142,168,378,908,687 is 5580479016.
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.
142 x 168 x 378 x 908 x 687 = 5625122848128
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.
142 : 1, 2, 71, 142
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
908 : 1, 2, 4, 227, 454, 908
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,168,378,908,687, is 1.
Now, the common factors can be found like this.
142:2x 71
168:2x 2x 2x 3x 7
378:2x 3x 3x 3x 7
908:2x 2x 227
687:3x 229
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 3x 3x 7 = 1008
Therefore, the value for common factors is 1008.
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 = 5625122848128/(1x1008)
LCM = 5625122848128/1008
LCM = 5580479016
Thus, we can understand that the LCM of 142,168,378,908,687 is 5580479016.
