Given numbers are 729,380,408,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,380,408,649 is 6112723320.
Find LCM of 729,380,408,649 with Prime Factorization
2 | 729, 380, 408, 649 |
2 | 729, 190, 204, 649 |
3 | 729, 95, 102, 649 |
243, 95, 34, 649 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 243 x 95 x 34 x 649 = 6112723320
Therefore, the lowest common multiple of 729,380,408,649 is 6112723320.
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.
729 x 380 x 408 x 649 = 73352679840
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.
729 : 1, 3, 9, 27, 81, 243, 729
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,380,408,649, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
380:2x 2x 5x 19
408:2x 2x 2x 3x 17
649:11x 59
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 3 = 12
Therefore, the value for common factors is 12.
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 = 73352679840/(1x12)
LCM = 73352679840/12
LCM = 6112723320
Thus, we can understand that the LCM of 729,380,408,649 is 6112723320.
