Given numbers are 863,957,557,609
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 863,957,557,609 is 3220149009.
Find LCM of 863,957,557,609 with Prime Factorization
| 3 | 863, 957, 557, 609 |
| 29 | 863, 319, 557, 203 |
| 863, 11, 557, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 29 x 863 x 11 x 557 x 7 = 3220149009
Therefore, the lowest common multiple of 863,957,557,609 is 3220149009.
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.
863 x 957 x 557 x 609 = 280152963783
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.
863 : 1, 863
957 : 1, 3, 11, 29, 33, 87, 319, 957
557 : 1, 557
609 : 1, 3, 7, 21, 29, 87, 203, 609
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,957,557,609, is 1.
Now, the common factors can be found like this.
863:863
957:3x 11x 29
557:557
609:3x 7x 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 29 = 87
Therefore, the value for common factors is 87.
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 = 280152963783/(1x87)
LCM = 280152963783/87
LCM = 3220149009
Thus, we can understand that the LCM of 863,957,557,609 is 3220149009.
