Given numbers are 685,861,747,747,114
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,861,747,747,114 is 5580545670.
Find LCM of 685,861,747,747,114 with Prime Factorization
| 3 | 685, 861, 747, 747, 114 |
| 3 | 685, 287, 249, 249, 38 |
| 83 | 685, 287, 83, 83, 38 |
| 685, 287, 1, 1, 38 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 83 x 685 x 287 x 1 x 1 x 38 = 5580545670
Therefore, the lowest common multiple of 685,861,747,747,114 is 5580545670.
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.
685 x 861 x 747 x 747 x 114 = 37518008539410
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.
685 : 1, 5, 137, 685
861 : 1, 3, 7, 21, 41, 123, 287, 861
747 : 1, 3, 9, 83, 249, 747
747 : 1, 3, 9, 83, 249, 747
114 : 1, 2, 3, 6, 19, 38, 57, 114
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,861,747,747,114, is 1.
Now, the common factors can be found like this.
685:5x 137
861:3x 7x 41
747:3x 3x 83
747:3x 3x 83
114:2x 3x 19
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 3x 3x 83 = 6723
Therefore, the value for common factors is 6723.
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 = 37518008539410/(1x6723)
LCM = 37518008539410/6723
LCM = 5580545670
Thus, we can understand that the LCM of 685,861,747,747,114 is 5580545670.
