Given numbers are 993,609,917,406
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 993,609,917,406 is 52813698.
Find LCM of 993,609,917,406 with Prime Factorization
| 3 | 993, 609, 917, 406 |
| 7 | 331, 203, 917, 406 |
| 29 | 331, 29, 131, 58 |
| 331, 1, 131, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 29 x 331 x 1 x 131 x 2 = 52813698
Therefore, the lowest common multiple of 993,609,917,406 is 52813698.
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 609 x 917 x 406 = 225144794574
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
609 : 1, 3, 7, 21, 29, 87, 203, 609
917 : 1, 7, 131, 917
406 : 1, 2, 7, 14, 29, 58, 203, 406
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,609,917,406, is 1.
Now, the common factors can be found like this.
993:3x 331
609:3x 7x 29
917:7x 131
406:2x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7x 29 = 4263
Therefore, the value for common factors is 4263.
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 = 225144794574/(1x4263)
LCM = 225144794574/4263
LCM = 52813698
Thus, we can understand that the LCM of 993,609,917,406 is 52813698.
