Find LCM of 781,891,387,513,344 with Prime Factorization
| 3 | 781, 891, 387, 513, 344 |
| 3 | 781, 297, 129, 171, 344 |
| 3 | 781, 99, 43, 57, 344 |
| 11 | 781, 33, 43, 19, 344 |
| 43 | 71, 3, 43, 19, 344 |
| 71, 3, 1, 19, 8 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 11 x 43 x 71 x 3 x 1 x 19 x 8 = 413473896
Therefore, the lowest common multiple of 781,891,387,513,344 is 413473896.
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.
781 x 891 x 387 x 513 x 344 = 47524276132344
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.
781 : 1, 11, 71, 781
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
387 : 1, 3, 9, 43, 129, 387
513 : 1, 3, 9, 19, 27, 57, 171, 513
344 : 1, 2, 4, 8, 43, 86, 172, 344
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,891,387,513,344, is 1.
Now, the common factors can be found like this.
781:11x 71
891:3x 3x 3x 3x 11
387:3x 3x 43
513:3x 3x 3x 19
344:2x 2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3x 11x 43 = 114939
Therefore, the value for common factors is 114939.
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 = 47524276132344/(1x114939)
LCM = 47524276132344/114939
LCM = 413473896
Thus, we can understand that the LCM of 781,891,387,513,344 is 413473896.
