Given numbers are 418,568,526,392,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,568,526,392,686 is 10708890808.
Find LCM of 418,568,526,392,686 with Prime Factorization
| 2 | 418, 568, 526, 392, 686 |
| 2 | 209, 284, 263, 196, 343 |
| 2 | 209, 142, 263, 98, 343 |
| 7 | 209, 71, 263, 49, 343 |
| 7 | 209, 71, 263, 7, 49 |
| 209, 71, 263, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 7 x 209 x 71 x 263 x 1 x 7 = 10708890808
Therefore, the lowest common multiple of 418,568,526,392,686 is 10708890808.
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.
418 x 568 x 526 x 392 x 686 = 33583081573888
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
568 : 1, 2, 4, 8, 71, 142, 284, 568
526 : 1, 2, 263, 526
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
686 : 1, 2, 7, 14, 49, 98, 343, 686
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,568,526,392,686, is 2.
Now, the common factors can be found like this.
418:2x 11x 19
568:2x 2x 2x 71
526:2x 263
392:2x 2x 2x 7x 7
686:2x 7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 7x 7 = 1568
Therefore, the value for common factors is 1568.
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 = 33583081573888/(2x1568)
LCM = 33583081573888/3136
LCM = 10708890808
Thus, we can understand that the LCM of 418,568,526,392,686 is 10708890808.
