Given numbers are 728,364,973,666
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 728,364,973,666 is 33696936.
Find LCM of 728,364,973,666 with Prime Factorization
| 2 | 728, 364, 973, 666 |
| 2 | 364, 182, 973, 333 |
| 7 | 91, 182, 973, 333 |
| 13 | 13, 26, 139, 333 |
| 1, 2, 139, 333 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 13 x 1 x 2 x 139 x 333 = 33696936
Therefore, the lowest common multiple of 728,364,973,666 is 33696936.
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.
728 x 364 x 973 x 666 = 171719585856
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
973 : 1, 7, 139, 973
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,364,973,666, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
364:2x 2x 7x 13
973:7x 139
666:2x 3x 3x 37
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 7x 7x 13 = 5096
Therefore, the value for common factors is 5096.
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 = 171719585856/(1x5096)
LCM = 171719585856/5096
LCM = 33696936
Thus, we can understand that the LCM of 728,364,973,666 is 33696936.
