Find LCM of 868,754,195,828,909 with Prime Factorization
| 2 | 868, 754, 195, 828, 909 |
| 2 | 434, 377, 195, 414, 909 |
| 3 | 217, 377, 195, 207, 909 |
| 3 | 217, 377, 65, 69, 303 |
| 13 | 217, 377, 65, 23, 101 |
| 217, 29, 5, 23, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 13 x 217 x 29 x 5 x 23 x 101 = 34207615260
Therefore, the lowest common multiple of 868,754,195,828,909 is 34207615260.
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.
868 x 754 x 195 x 828 x 909 = 96054983650080
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.
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
754 : 1, 2, 13, 26, 29, 58, 377, 754
195 : 1, 3, 5, 13, 15, 39, 65, 195
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,754,195,828,909, is 1.
Now, the common factors can be found like this.
868:2x 2x 7x 31
754:2x 13x 29
195:3x 5x 13
828:2x 2x 3x 3x 23
909:3x 3x 101
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 3x 13 = 2808
Therefore, the value for common factors is 2808.
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 = 96054983650080/(1x2808)
LCM = 96054983650080/2808
LCM = 34207615260
Thus, we can understand that the LCM of 868,754,195,828,909 is 34207615260.
