Given numbers are 371,915,405,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 371,915,405,688 is 6305901840.
Find LCM of 371,915,405,688 with Prime Factorization
| 3 | 371, 915, 405, 688 |
| 5 | 371, 305, 135, 688 |
| 371, 61, 27, 688 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 371 x 61 x 27 x 688 = 6305901840
Therefore, the lowest common multiple of 371,915,405,688 is 6305901840.
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.
371 x 915 x 405 x 688 = 94588527600
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.
371 : 1, 7, 53, 371
915 : 1, 3, 5, 15, 61, 183, 305, 915
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 371,915,405,688, is 1.
Now, the common factors can be found like this.
371:7x 53
915:3x 5x 61
405:3x 3x 3x 3x 5
688:2x 2x 2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 94588527600/(1x15)
LCM = 94588527600/15
LCM = 6305901840
Thus, we can understand that the LCM of 371,915,405,688 is 6305901840.
