Given numbers are 717,218,726,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,218,726,748 is 643042884.
Find LCM of 717,218,726,748 with Prime Factorization
| 2 | 717, 218, 726, 748 |
| 3 | 717, 109, 363, 374 |
| 11 | 239, 109, 121, 374 |
| 239, 109, 11, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 239 x 109 x 11 x 34 = 643042884
Therefore, the lowest common multiple of 717,218,726,748 is 643042884.
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.
717 x 218 x 726 x 748 = 84881660688
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.
717 : 1, 3, 239, 717
218 : 1, 2, 109, 218
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,218,726,748, is 1.
Now, the common factors can be found like this.
717:3x 239
218:2x 109
726:2x 3x 11x 11
748:2x 2x 11x 17
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 11 = 132
Therefore, the value for common factors is 132.
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 = 84881660688/(1x132)
LCM = 84881660688/132
LCM = 643042884
Thus, we can understand that the LCM of 717,218,726,748 is 643042884.
