Given numbers are 811,161,660,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,161,660,678 is 9737985180.
Find LCM of 811,161,660,678 with Prime Factorization
| 2 | 811, 161, 660, 678 |
| 3 | 811, 161, 330, 339 |
| 811, 161, 110, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 811 x 161 x 110 x 113 = 9737985180
Therefore, the lowest common multiple of 811,161,660,678 is 9737985180.
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.
811 x 161 x 660 x 678 = 58427911080
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.
811 : 1, 811
161 : 1, 7, 23, 161
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,161,660,678, is 1.
Now, the common factors can be found like this.
811:811
161:7x 23
660:2x 2x 3x 5x 11
678:2x 3x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 58427911080/(1x6)
LCM = 58427911080/6
LCM = 9737985180
Thus, we can understand that the LCM of 811,161,660,678 is 9737985180.
