Given numbers are 806,609,985,361,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 806,609,985,361,788 is 349080639180.
Find LCM of 806,609,985,361,788 with Prime Factorization
| 2 | 806, 609, 985, 361, 788 |
| 197 | 403, 609, 985, 361, 394 |
| 403, 609, 5, 361, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 197 x 403 x 609 x 5 x 361 x 2 = 349080639180
Therefore, the lowest common multiple of 806,609,985,361,788 is 349080639180.
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.
806 x 609 x 985 x 361 x 788 = 137537771836920
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
609 : 1, 3, 7, 21, 29, 87, 203, 609
985 : 1, 5, 197, 985
361 : 1, 19, 361
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,609,985,361,788, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
609:3x 7x 29
985:5x 197
361:19x 19
788:2x 2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 197 = 394
Therefore, the value for common factors is 394.
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 = 137537771836920/(1x394)
LCM = 137537771836920/394
LCM = 349080639180
Thus, we can understand that the LCM of 806,609,985,361,788 is 349080639180.
