Given numbers are 781,726,497,268,118
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,726,497,268,118 is 2852658732.
Find LCM of 781,726,497,268,118 with Prime Factorization
| 2 | 781, 726, 497, 268, 118 |
| 11 | 781, 363, 497, 134, 59 |
| 71 | 71, 33, 497, 134, 59 |
| 1, 33, 7, 134, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 71 x 1 x 33 x 7 x 134 x 59 = 2852658732
Therefore, the lowest common multiple of 781,726,497,268,118 is 2852658732.
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 726 x 497 x 268 x 118 = 8911705878768
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
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
497 : 1, 7, 71, 497
268 : 1, 2, 4, 67, 134, 268
118 : 1, 2, 59, 118
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,726,497,268,118, is 1.
Now, the common factors can be found like this.
781:11x 71
726:2x 3x 11x 11
497:7x 71
268:2x 2x 67
118:2x 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 11x 71 = 3124
Therefore, the value for common factors is 3124.
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 = 8911705878768/(1x3124)
LCM = 8911705878768/3124
LCM = 2852658732
Thus, we can understand that the LCM of 781,726,497,268,118 is 2852658732.
