The LCM of 721,826,136,843,354 is 4877011272.
Find LCM of 721,826,136,843,354 with Prime Factorization
| 2 | 721, 826, 136, 843, 354 |
| 3 | 721, 413, 68, 843, 177 |
| 7 | 721, 413, 68, 281, 59 |
| 59 | 103, 59, 68, 281, 59 |
| 103, 1, 68, 281, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 59 x 103 x 1 x 68 x 281 x 1 = 4877011272
Therefore, the lowest common multiple of 721,826,136,843,354 is 4877011272.
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.
721 x 826 x 136 x 843 x 354 = 24170467864032
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.
721 : 1, 7, 103, 721
826 : 1, 2, 7, 14, 59, 118, 413, 826
136 : 1, 2, 4, 8, 17, 34, 68, 136
843 : 1, 3, 281, 843
354 : 1, 2, 3, 6, 59, 118, 177, 354
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,826,136,843,354, is 1.
Now, the common factors can be found like this.
721:7x 103
826:2x 7x 59
136:2x 2x 2x 17
843:3x 281
354:2x 3x 59
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 3x 7x 59 = 4956
Therefore, the value for common factors is 4956.
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 = 24170467864032/(1x4956)
LCM = 24170467864032/4956
LCM = 4877011272
Thus, we can understand that the LCM of 721,826,136,843,354 is 4877011272.
