The LCM of 364,807,945,868 is 409778460.
Find LCM of 364,807,945,868 with Prime Factorization
| 2 | 364, 807, 945, 868 |
| 2 | 182, 807, 945, 434 |
| 3 | 91, 807, 945, 217 |
| 7 | 91, 269, 315, 217 |
| 13, 269, 45, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 13 x 269 x 45 x 31 = 409778460
Therefore, the lowest common multiple of 364,807,945,868 is 409778460.
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.
364 x 807 x 945 x 868 = 240949734480
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.
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
807 : 1, 3, 269, 807
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 364,807,945,868, is 1.
Now, the common factors can be found like this.
364:2x 2x 7x 13
807:3x 269
945:3x 3x 3x 5x 7
868:2x 2x 7x 31
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 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 240949734480/(1x588)
LCM = 240949734480/588
LCM = 409778460
Thus, we can understand that the LCM of 364,807,945,868 is 409778460.
