Given numbers are 726,874,921,616
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 726,874,921,616 is 2727184152.
Find LCM of 726,874,921,616 with Prime Factorization
| 2 | 726, 874, 921, 616 |
| 3 | 363, 437, 921, 308 |
| 11 | 121, 437, 307, 308 |
| 11, 437, 307, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 11 x 437 x 307 x 28 = 2727184152
Therefore, the lowest common multiple of 726,874,921,616 is 2727184152.
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.
726 x 874 x 921 x 616 = 359988308064
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.
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
874 : 1, 2, 19, 23, 38, 46, 437, 874
921 : 1, 3, 307, 921
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 726,874,921,616, is 1.
Now, the common factors can be found like this.
726:2x 3x 11x 11
874:2x 19x 23
921:3x 307
616:2x 2x 2x 7x 11
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 = 359988308064/(1x132)
LCM = 359988308064/132
LCM = 2727184152
Thus, we can understand that the LCM of 726,874,921,616 is 2727184152.
