Find LCM of 392,943,891,138,836 with Prime Factorization
| 2 | 392, 943, 891, 138, 836 |
| 2 | 196, 943, 891, 69, 418 |
| 3 | 98, 943, 891, 69, 209 |
| 11 | 98, 943, 297, 23, 209 |
| 23 | 98, 943, 27, 23, 19 |
| 98, 41, 27, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 23 x 98 x 41 x 27 x 1 x 19 = 6257906424
Therefore, the lowest common multiple of 392,943,891,138,836 is 6257906424.
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.
392 x 943 x 891 x 138 x 836 = 37998007806528
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
943 : 1, 23, 41, 943
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
138 : 1, 2, 3, 6, 23, 46, 69, 138
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,943,891,138,836, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
943:23x 41
891:3x 3x 3x 3x 11
138:2x 3x 23
836:2x 2x 11x 19
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 3x 11x 23 = 6072
Therefore, the value for common factors is 6072.
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 = 37998007806528/(1x6072)
LCM = 37998007806528/6072
LCM = 6257906424
Thus, we can understand that the LCM of 392,943,891,138,836 is 6257906424.
