Given numbers are 399,809,649,246,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,809,649,246,756 is 309209245884.
Find LCM of 399,809,649,246,756 with Prime Factorization
| 2 | 399, 809, 649, 246, 756 |
| 3 | 399, 809, 649, 123, 378 |
| 7 | 133, 809, 649, 41, 126 |
| 19, 809, 649, 41, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 19 x 809 x 649 x 41 x 18 = 309209245884
Therefore, the lowest common multiple of 399,809,649,246,756 is 309209245884.
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.
399 x 809 x 649 x 246 x 756 = 38960364981384
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
809 : 1, 809
649 : 1, 11, 59, 649
246 : 1, 2, 3, 6, 41, 82, 123, 246
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,809,649,246,756, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
809:809
649:11x 59
246:2x 3x 41
756:2x 2x 3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 38960364981384/(1x126)
LCM = 38960364981384/126
LCM = 309209245884
Thus, we can understand that the LCM of 399,809,649,246,756 is 309209245884.
