Given numbers are 612,861,858,216
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 612,861,858,216 is 150702552.
Find LCM of 612,861,858,216 with Prime Factorization
| 2 | 612, 861, 858, 216 |
| 2 | 306, 861, 429, 108 |
| 3 | 153, 861, 429, 54 |
| 3 | 51, 287, 143, 18 |
| 17, 287, 143, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 17 x 287 x 143 x 6 = 150702552
Therefore, the lowest common multiple of 612,861,858,216 is 150702552.
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.
612 x 861 x 858 x 216 = 97655253696
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.
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
861 : 1, 3, 7, 21, 41, 123, 287, 861
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,861,858,216, is 3.
Now, the common factors can be found like this.
612:2x 2x 3x 3x 17
861:3x 7x 41
858:2x 3x 11x 13
216:2x 2x 2x 3x 3x 3
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 97655253696/(3x216)
LCM = 97655253696/648
LCM = 150702552
Thus, we can understand that the LCM of 612,861,858,216 is 150702552.
