Given numbers are 378,861,807,261,345
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 378,861,807,261,345 is 13903488270.
Find LCM of 378,861,807,261,345 with Prime Factorization
| 3 | 378, 861, 807, 261, 345 |
| 3 | 126, 287, 269, 87, 115 |
| 7 | 42, 287, 269, 29, 115 |
| 6, 41, 269, 29, 115 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 6 x 41 x 269 x 29 x 115 = 13903488270
Therefore, the lowest common multiple of 378,861,807,261,345 is 13903488270.
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.
378 x 861 x 807 x 261 x 345 = 23649833547270
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
861 : 1, 3, 7, 21, 41, 123, 287, 861
807 : 1, 3, 269, 807
261 : 1, 3, 9, 29, 87, 261
345 : 1, 3, 5, 15, 23, 69, 115, 345
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,861,807,261,345, is 3.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
861:3x 7x 41
807:3x 269
261:3x 3x 29
345:3x 5x 23
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 3x 7 = 567
Therefore, the value for common factors is 567.
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 = 23649833547270/(3x567)
LCM = 23649833547270/1701
LCM = 13903488270
Thus, we can understand that the LCM of 378,861,807,261,345 is 13903488270.
