Given numbers are 107,621,940,591,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 107,621,940,591,987 is 86132588220.
Find LCM of 107,621,940,591,987 with Prime Factorization
| 3 | 107, 621, 940, 591, 987 |
| 47 | 107, 207, 940, 197, 329 |
| 107, 207, 20, 197, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 47 x 107 x 207 x 20 x 197 x 7 = 86132588220
Therefore, the lowest common multiple of 107,621,940,591,987 is 86132588220.
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.
107 x 621 x 940 x 591 x 987 = 36434084817060
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.
107 : 1, 107
621 : 1, 3, 9, 23, 27, 69, 207, 621
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
591 : 1, 3, 197, 591
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 107,621,940,591,987, is 1.
Now, the common factors can be found like this.
107:107
621:3x 3x 3x 23
940:2x 2x 5x 47
591:3x 197
987:3x 7x 47
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 47 = 423
Therefore, the value for common factors is 423.
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 = 36434084817060/(1x423)
LCM = 36434084817060/423
LCM = 86132588220
Thus, we can understand that the LCM of 107,621,940,591,987 is 86132588220.
