The LCM of 813,623,351,666,469 is 293812978914.
Find LCM of 813,623,351,666,469 with Prime Factorization
| 3 | 813, 623, 351, 666, 469 |
| 3 | 271, 623, 117, 222, 469 |
| 7 | 271, 623, 39, 74, 469 |
| 271, 89, 39, 74, 67 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 271 x 89 x 39 x 74 x 67 = 293812978914
Therefore, the lowest common multiple of 813,623,351,666,469 is 293812978914.
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.
813 x 623 x 351 x 666 x 469 = 55530653014746
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.
813 : 1, 3, 271, 813
623 : 1, 7, 89, 623
351 : 1, 3, 9, 13, 27, 39, 117, 351
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
469 : 1, 7, 67, 469
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,623,351,666,469, is 1.
Now, the common factors can be found like this.
813:3x 271
623:7x 89
351:3x 3x 3x 13
666:2x 3x 3x 37
469:7x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 55530653014746/(1x189)
LCM = 55530653014746/189
LCM = 293812978914
Thus, we can understand that the LCM of 813,623,351,666,469 is 293812978914.
