Given numbers are 816,152,898,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,152,898,648 is 187954992.
Find LCM of 816,152,898,648 with Prime Factorization
| 2 | 816, 152, 898, 648 |
| 2 | 408, 76, 449, 324 |
| 2 | 204, 38, 449, 162 |
| 3 | 102, 19, 449, 81 |
| 34, 19, 449, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 34 x 19 x 449 x 27 = 187954992
Therefore, the lowest common multiple of 816,152,898,648 is 187954992.
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.
816 x 152 x 898 x 648 = 72174716928
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
152 : 1, 2, 4, 8, 19, 38, 76, 152
898 : 1, 2, 449, 898
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,152,898,648, is 2.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
152:2x 2x 2x 19
898:2x 449
648:2x 2x 2x 3x 3x 3x 3
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 3 = 192
Therefore, the value for common factors is 192.
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 = 72174716928/(2x192)
LCM = 72174716928/384
LCM = 187954992
Thus, we can understand that the LCM of 816,152,898,648 is 187954992.
