Given numbers are 661,591,538,957,960
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,591,538,957,960 is 10727088947520.
Find LCM of 661,591,538,957,960 with Prime Factorization
| 2 | 661, 591, 538, 957, 960 |
| 3 | 661, 591, 269, 957, 480 |
| 661, 197, 269, 319, 160 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 661 x 197 x 269 x 319 x 160 = 10727088947520
Therefore, the lowest common multiple of 661,591,538,957,960 is 10727088947520.
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.
661 x 591 x 538 x 957 x 960 = 193087601055360
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.
661 : 1, 661
591 : 1, 3, 197, 591
538 : 1, 2, 269, 538
957 : 1, 3, 11, 29, 33, 87, 319, 957
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,591,538,957,960, is 1.
Now, the common factors can be found like this.
661:661
591:3x 197
538:2x 269
957:3x 11x 29
960:2x 2x 2x 2x 2x 2x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 193087601055360/(1x18)
LCM = 193087601055360/18
LCM = 10727088947520
Thus, we can understand that the LCM of 661,591,538,957,960 is 10727088947520.
