The LCM of 411,738,918,782 is 118597338.
Find LCM of 411,738,918,782 with Prime Factorization
| 2 | 411, 738, 918, 782 |
| 3 | 411, 369, 459, 391 |
| 3 | 137, 123, 153, 391 |
| 17 | 137, 41, 51, 391 |
| 137, 41, 3, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 137 x 41 x 3 x 23 = 118597338
Therefore, the lowest common multiple of 411,738,918,782 is 118597338.
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.
411 x 738 x 918 x 782 = 217744712568
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.
411 : 1, 3, 137, 411
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 411,738,918,782, is 1.
Now, the common factors can be found like this.
411:3x 137
738:2x 3x 3x 41
918:2x 3x 3x 3x 17
782:2x 17x 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 3x 3x 3x 17 = 1836
Therefore, the value for common factors is 1836.
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 = 217744712568/(1x1836)
LCM = 217744712568/1836
LCM = 118597338
Thus, we can understand that the LCM of 411,738,918,782 is 118597338.
