Given numbers are 382,878,441,691,343
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 382,878,441,691,343 is 357719454666.
Find LCM of 382,878,441,691,343 with Prime Factorization
| 2 | 382, 878, 441, 691, 343 |
| 7 | 191, 439, 441, 691, 343 |
| 7 | 191, 439, 63, 691, 49 |
| 191, 439, 9, 691, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 191 x 439 x 9 x 691 x 7 = 357719454666
Therefore, the lowest common multiple of 382,878,441,691,343 is 357719454666.
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.
382 x 878 x 441 x 691 x 343 = 35056506557268
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.
382 : 1, 2, 191, 382
878 : 1, 2, 439, 878
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
691 : 1, 691
343 : 1, 7, 49, 343
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,878,441,691,343, is 1.
Now, the common factors can be found like this.
382:2x 191
878:2x 439
441:3x 3x 7x 7
691:691
343:7x 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 7x 7 = 98
Therefore, the value for common factors is 98.
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 = 35056506557268/(1x98)
LCM = 35056506557268/98
LCM = 357719454666
Thus, we can understand that the LCM of 382,878,441,691,343 is 357719454666.
