Find LCM of 619,981,249,442,858 with Prime Factorization
| 2 | 619, 981, 249, 442, 858 |
| 3 | 619, 981, 249, 221, 429 |
| 13 | 619, 327, 83, 221, 143 |
| 619, 327, 83, 17, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 619 x 327 x 83 x 17 x 11 = 245048869494
Therefore, the lowest common multiple of 619,981,249,442,858 is 245048869494.
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.
619 x 981 x 249 x 442 x 858 = 57341435461596
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.
619 : 1, 619
981 : 1, 3, 9, 109, 327, 981
249 : 1, 3, 83, 249
442 : 1, 2, 13, 17, 26, 34, 221, 442
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,981,249,442,858, is 1.
Now, the common factors can be found like this.
619:619
981:3x 3x 109
249:3x 83
442:2x 13x 17
858:2x 3x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 13 = 234
Therefore, the value for common factors is 234.
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 = 57341435461596/(1x234)
LCM = 57341435461596/234
LCM = 245048869494
Thus, we can understand that the LCM of 619,981,249,442,858 is 245048869494.
