Given numbers are 449,786,690,810,701
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 449,786,690,810,701 is 768154376970.
Find LCM of 449,786,690,810,701 with Prime Factorization
| 2 | 449, 786, 690, 810, 701 |
| 3 | 449, 393, 345, 405, 701 |
| 5 | 449, 131, 115, 135, 701 |
| 449, 131, 23, 27, 701 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 449 x 131 x 23 x 27 x 701 = 768154376970
Therefore, the lowest common multiple of 449,786,690,810,701 is 768154376970.
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.
449 x 786 x 690 x 810 x 701 = 138267787854600
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.
449 : 1, 449
786 : 1, 2, 3, 6, 131, 262, 393, 786
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
701 : 1, 701
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,786,690,810,701, is 1.
Now, the common factors can be found like this.
449:449
786:2x 3x 131
690:2x 3x 5x 23
810:2x 3x 3x 3x 3x 5
701:701
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 5 = 180
Therefore, the value for common factors is 180.
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 = 138267787854600/(1x180)
LCM = 138267787854600/180
LCM = 768154376970
Thus, we can understand that the LCM of 449,786,690,810,701 is 768154376970.
