Given numbers are 343,471,806,420,187
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 343,471,806,420,187 is 243495912660.
Find LCM of 343,471,806,420,187 with Prime Factorization
| 2 | 343, 471, 806, 420, 187 |
| 3 | 343, 471, 403, 210, 187 |
| 7 | 343, 157, 403, 70, 187 |
| 49, 157, 403, 10, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 49 x 157 x 403 x 10 x 187 = 243495912660
Therefore, the lowest common multiple of 343,471,806,420,187 is 243495912660.
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.
343 x 471 x 806 x 420 x 187 = 10226828331720
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.
343 : 1, 7, 49, 343
471 : 1, 3, 157, 471
806 : 1, 2, 13, 26, 31, 62, 403, 806
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
187 : 1, 11, 17, 187
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,471,806,420,187, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
471:3x 157
806:2x 13x 31
420:2x 2x 3x 5x 7
187:11x 17
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 7 = 42
Therefore, the value for common factors is 42.
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 = 10226828331720/(1x42)
LCM = 10226828331720/42
LCM = 243495912660
Thus, we can understand that the LCM of 343,471,806,420,187 is 243495912660.
