Given numbers are 806,181,972,935,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 806,181,972,935,138 is 1524717316980.
Find LCM of 806,181,972,935,138 with Prime Factorization
| 2 | 806, 181, 972, 935, 138 |
| 3 | 403, 181, 486, 935, 69 |
| 403, 181, 162, 935, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 403 x 181 x 162 x 935 x 23 = 1524717316980
Therefore, the lowest common multiple of 806,181,972,935,138 is 1524717316980.
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.
806 x 181 x 972 x 935 x 138 = 18296607803760
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
181 : 1, 181
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
935 : 1, 5, 11, 17, 55, 85, 187, 935
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,181,972,935,138, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
181:181
972:2x 2x 3x 3x 3x 3x 3
935:5x 11x 17
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 18296607803760/(1x12)
LCM = 18296607803760/12
LCM = 1524717316980
Thus, we can understand that the LCM of 806,181,972,935,138 is 1524717316980.
