Find LCM of 858,654,234,981 with Prime Factorization
| 2 | 858, 654, 234, 981 |
| 3 | 429, 327, 117, 981 |
| 3 | 143, 109, 39, 327 |
| 13 | 143, 109, 13, 109 |
| 109 | 11, 109, 1, 109 |
| 11, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 109 x 11 x 1 x 1 x 1 = 280566
Therefore, the lowest common multiple of 858,654,234,981 is 280566.
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.
858 x 654 x 234 x 981 = 128810095128
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
654 : 1, 2, 3, 6, 109, 218, 327, 654
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
981 : 1, 3, 9, 109, 327, 981
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,654,234,981, is 3.
Now, the common factors can be found like this.
858:2x 3x 11x 13
654:2x 3x 109
234:2x 3x 3x 13
981:3x 3x 109
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 13x 109 = 153036
Therefore, the value for common factors is 153036.
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 = 128810095128/(3x153036)
LCM = 128810095128/459108
LCM = 280566
Thus, we can understand that the LCM of 858,654,234,981 is 280566.
