Find LCM of 909,638,858,947,668 with Prime Factorization
2 | 909, 638, 858, 947, 668 |
3 | 909, 319, 429, 947, 334 |
11 | 303, 319, 143, 947, 334 |
303, 29, 13, 947, 334 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 303 x 29 x 13 x 947 x 334 = 2384648431308
Therefore, the lowest common multiple of 909,638,858,947,668 is 2384648431308.
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.
909 x 638 x 858 x 947 x 668 = 314773592932656
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.
909 : 1, 3, 9, 101, 303, 909
638 : 1, 2, 11, 22, 29, 58, 319, 638
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
947 : 1, 947
668 : 1, 2, 4, 167, 334, 668
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,638,858,947,668, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
638:2x 11x 29
858:2x 3x 11x 13
947:947
668:2x 2x 167
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 = 314773592932656/(1x132)
LCM = 314773592932656/132
LCM = 2384648431308
Thus, we can understand that the LCM of 909,638,858,947,668 is 2384648431308.
