Given numbers are 186,840,972,718,667
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 186,840,972,718,667 is 505063845720.
Find LCM of 186,840,972,718,667 with Prime Factorization
| 2 | 186, 840, 972, 718, 667 |
| 2 | 93, 420, 486, 359, 667 |
| 3 | 93, 210, 243, 359, 667 |
| 31, 70, 81, 359, 667 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 31 x 70 x 81 x 359 x 667 = 505063845720
Therefore, the lowest common multiple of 186,840,972,718,667 is 505063845720.
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.
186 x 840 x 972 x 718 x 667 = 72729193783680
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.
186 : 1, 2, 3, 6, 31, 62, 93, 186
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
718 : 1, 2, 359, 718
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 186,840,972,718,667, is 1.
Now, the common factors can be found like this.
186:2x 3x 31
840:2x 2x 2x 3x 5x 7
972:2x 2x 3x 3x 3x 3x 3
718:2x 359
667:23x 29
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 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 72729193783680/(1x144)
LCM = 72729193783680/144
LCM = 505063845720
Thus, we can understand that the LCM of 186,840,972,718,667 is 505063845720.
