Given numbers are 993,717,678,694
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 993,717,678,694 is 18611657994.
Find LCM of 993,717,678,694 with Prime Factorization
| 2 | 993, 717, 678, 694 |
| 3 | 993, 717, 339, 347 |
| 331, 239, 113, 347 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 331 x 239 x 113 x 347 = 18611657994
Therefore, the lowest common multiple of 993,717,678,694 is 18611657994.
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.
993 x 717 x 678 x 694 = 335009843892
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.
993 : 1, 3, 331, 993
717 : 1, 3, 239, 717
678 : 1, 2, 3, 6, 113, 226, 339, 678
694 : 1, 2, 347, 694
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,717,678,694, is 1.
Now, the common factors can be found like this.
993:3x 331
717:3x 239
678:2x 3x 113
694:2x 347
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 335009843892/(1x18)
LCM = 335009843892/18
LCM = 18611657994
Thus, we can understand that the LCM of 993,717,678,694 is 18611657994.
