Given numbers are 869,858,646,870,863
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,858,646,870,863 is 2739653884110.
Find LCM of 869,858,646,870,863 with Prime Factorization
| 2 | 869, 858, 646, 870, 863 |
| 3 | 869, 429, 323, 435, 863 |
| 11 | 869, 143, 323, 145, 863 |
| 79, 13, 323, 145, 863 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 79 x 13 x 323 x 145 x 863 = 2739653884110
Therefore, the lowest common multiple of 869,858,646,870,863 is 2739653884110.
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.
869 x 858 x 646 x 870 x 863 = 361634312702520
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.
869 : 1, 11, 79, 869
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
646 : 1, 2, 17, 19, 34, 38, 323, 646
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
863 : 1, 863
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,858,646,870,863, is 1.
Now, the common factors can be found like this.
869:11x 79
858:2x 3x 11x 13
646:2x 17x 19
870:2x 3x 5x 29
863:863
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 361634312702520/(1x132)
LCM = 361634312702520/132
LCM = 2739653884110
Thus, we can understand that the LCM of 869,858,646,870,863 is 2739653884110.
