Given numbers are 107,399,655,690,783
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 107,399,655,690,783 is 335734763490.
Find LCM of 107,399,655,690,783 with Prime Factorization
| 3 | 107, 399, 655, 690, 783 |
| 5 | 107, 133, 655, 230, 261 |
| 107, 133, 131, 46, 261 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 107 x 133 x 131 x 46 x 261 = 335734763490
Therefore, the lowest common multiple of 107,399,655,690,783 is 335734763490.
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.
107 x 399 x 655 x 690 x 783 = 15108064357050
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.
107 : 1, 107
399 : 1, 3, 7, 19, 21, 57, 133, 399
655 : 1, 5, 131, 655
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
783 : 1, 3, 9, 27, 29, 87, 261, 783
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 107,399,655,690,783, is 1.
Now, the common factors can be found like this.
107:107
399:3x 7x 19
655:5x 131
690:2x 3x 5x 23
783:3x 3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5 = 45
Therefore, the value for common factors is 45.
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 = 15108064357050/(1x45)
LCM = 15108064357050/45
LCM = 335734763490
Thus, we can understand that the LCM of 107,399,655,690,783 is 335734763490.
