Given numbers are 766,667,391,686,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,667,391,686,816 is 71500468368.
Find LCM of 766,667,391,686,816 with Prime Factorization
| 2 | 766, 667, 391, 686, 816 |
| 17 | 383, 667, 391, 343, 408 |
| 23 | 383, 667, 23, 343, 24 |
| 383, 29, 1, 343, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 383 x 29 x 1 x 343 x 24 = 71500468368
Therefore, the lowest common multiple of 766,667,391,686,816 is 71500468368.
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.
766 x 667 x 391 x 686 x 816 = 111826732527552
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.
766 : 1, 2, 383, 766
667 : 1, 23, 29, 667
391 : 1, 17, 23, 391
686 : 1, 2, 7, 14, 49, 98, 343, 686
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,667,391,686,816, is 1.
Now, the common factors can be found like this.
766:2x 383
667:23x 29
391:17x 23
686:2x 7x 7x 7
816:2x 2x 2x 2x 3x 17
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 17x 23 = 1564
Therefore, the value for common factors is 1564.
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 = 111826732527552/(1x1564)
LCM = 111826732527552/1564
LCM = 71500468368
Thus, we can understand that the LCM of 766,667,391,686,816 is 71500468368.
