Find LCM of 818,643,358,576,736 with Prime Factorization
| 2 | 818, 643, 358, 576, 736 |
| 2 | 409, 643, 179, 288, 368 |
| 2 | 409, 643, 179, 144, 184 |
| 2 | 409, 643, 179, 72, 92 |
| 2 | 409, 643, 179, 36, 46 |
| 409, 643, 179, 18, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 409 x 643 x 179 x 18 x 23 = 623645267904
Therefore, the lowest common multiple of 818,643,358,576,736 is 623645267904.
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.
818 x 643 x 358 x 576 x 736 = 79826594291712
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.
818 : 1, 2, 409, 818
643 : 1, 643
358 : 1, 2, 179, 358
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,643,358,576,736, is 1.
Now, the common factors can be found like this.
818:2x 409
643:643
358:2x 179
576:2x 2x 2x 2x 2x 2x 3x 3
736:2x 2x 2x 2x 2x 23
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 2x 2x 2x 2 = 128
Therefore, the value for common factors is 128.
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 = 79826594291712/(1x128)
LCM = 79826594291712/128
LCM = 623645267904
Thus, we can understand that the LCM of 818,643,358,576,736 is 623645267904.
