The LCM of 718,920,654,869,396 is 281560066920.
Find LCM of 718,920,654,869,396 with Prime Factorization
| 2 | 718, 920, 654, 869, 396 |
| 2 | 359, 460, 327, 869, 198 |
| 3 | 359, 230, 327, 869, 99 |
| 11 | 359, 230, 109, 869, 33 |
| 359, 230, 109, 79, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 359 x 230 x 109 x 79 x 3 = 281560066920
Therefore, the lowest common multiple of 718,920,654,869,396 is 281560066920.
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.
718 x 920 x 654 x 869 x 396 = 148663715333760
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.
718 : 1, 2, 359, 718
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
654 : 1, 2, 3, 6, 109, 218, 327, 654
869 : 1, 11, 79, 869
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 718,920,654,869,396, is 1.
Now, the common factors can be found like this.
718:2x 359
920:2x 2x 2x 5x 23
654:2x 3x 109
869:11x 79
396:2x 2x 3x 3x 11
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 11 = 528
Therefore, the value for common factors is 528.
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 = 148663715333760/(1x528)
LCM = 148663715333760/528
LCM = 281560066920
Thus, we can understand that the LCM of 718,920,654,869,396 is 281560066920.
