Find LCM of 981,818,488,544,549 with Prime Factorization
| 2 | 981, 818, 488, 544, 549 |
| 2 | 981, 409, 244, 272, 549 |
| 2 | 981, 409, 122, 136, 549 |
| 3 | 981, 409, 61, 68, 549 |
| 3 | 327, 409, 61, 68, 183 |
| 61 | 109, 409, 61, 68, 61 |
| 109, 409, 1, 68, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 61 x 109 x 409 x 1 x 68 x 1 = 13314383136
Therefore, the lowest common multiple of 981,818,488,544,549 is 13314383136.
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.
981 x 818 x 488 x 544 x 549 = 116953541466624
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.
981 : 1, 3, 9, 109, 327, 981
818 : 1, 2, 409, 818
488 : 1, 2, 4, 8, 61, 122, 244, 488
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
549 : 1, 3, 9, 61, 183, 549
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,818,488,544,549, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
818:2x 409
488:2x 2x 2x 61
544:2x 2x 2x 2x 2x 17
549:3x 3x 61
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 61 = 8784
Therefore, the value for common factors is 8784.
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 = 116953541466624/(1x8784)
LCM = 116953541466624/8784
LCM = 13314383136
Thus, we can understand that the LCM of 981,818,488,544,549 is 13314383136.
