Given numbers are 315,645,645,957
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,645,645,957 is 4320855.
Find LCM of 315,645,645,957 with Prime Factorization
| 3 | 315, 645, 645, 957 |
| 5 | 105, 215, 215, 319 |
| 43 | 21, 43, 43, 319 |
| 21, 1, 1, 319 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 43 x 21 x 1 x 1 x 319 = 4320855
Therefore, the lowest common multiple of 315,645,645,957 is 4320855.
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.
315 x 645 x 645 x 957 = 125412816375
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
645 : 1, 3, 5, 15, 43, 129, 215, 645
645 : 1, 3, 5, 15, 43, 129, 215, 645
957 : 1, 3, 11, 29, 33, 87, 319, 957
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,645,645,957, is 3.
Now, the common factors can be found like this.
315:3x 3x 5x 7
645:3x 5x 43
645:3x 5x 43
957:3x 11x 29
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 5x 5x 43 = 9675
Therefore, the value for common factors is 9675.
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 = 125412816375/(3x9675)
LCM = 125412816375/29025
LCM = 4320855
Thus, we can understand that the LCM of 315,645,645,957 is 4320855.
