Given numbers are 126,900,649,408
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 126,900,649,408 is 139015800.
Find LCM of 126,900,649,408 with Prime Factorization
| 2 | 126, 900, 649, 408 |
| 2 | 63, 450, 649, 204 |
| 3 | 63, 225, 649, 102 |
| 3 | 21, 75, 649, 34 |
| 7, 25, 649, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 25 x 649 x 34 = 139015800
Therefore, the lowest common multiple of 126,900,649,408 is 139015800.
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.
126 x 900 x 649 x 408 = 30027412800
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.
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
649 : 1, 11, 59, 649
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,900,649,408, is 1.
Now, the common factors can be found like this.
126:2x 3x 3x 7
900:2x 2x 3x 3x 5x 5
649:11x 59
408:2x 2x 2x 3x 17
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 2x 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 30027412800/(1x216)
LCM = 30027412800/216
LCM = 139015800
Thus, we can understand that the LCM of 126,900,649,408 is 139015800.
