Find LCM of 903,455,703,858,869 with Prime Factorization
3 | 903, 455, 703, 858, 869 |
7 | 301, 455, 703, 286, 869 |
11 | 43, 65, 703, 286, 869 |
13 | 43, 65, 703, 26, 79 |
43, 5, 703, 2, 79 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 13 x 43 x 5 x 703 x 2 x 79 = 71714372730
Therefore, the lowest common multiple of 903,455,703,858,869 is 71714372730.
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.
903 x 455 x 703 x 858 x 869 = 215358261308190
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.
903 : 1, 3, 7, 21, 43, 129, 301, 903
455 : 1, 5, 7, 13, 35, 65, 91, 455
703 : 1, 19, 37, 703
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,455,703,858,869, is 1.
Now, the common factors can be found like this.
903:3x 7x 43
455:5x 7x 13
703:19x 37
858:2x 3x 11x 13
869:11x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 11x 13 = 3003
Therefore, the value for common factors is 3003.
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 = 215358261308190/(1x3003)
LCM = 215358261308190/3003
LCM = 71714372730
Thus, we can understand that the LCM of 903,455,703,858,869 is 71714372730.
