Given numbers are 685,810,231,943,657
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,810,231,943,657 is 588207914910.
Find LCM of 685,810,231,943,657 with Prime Factorization
| 3 | 685, 810, 231, 943, 657 |
| 3 | 685, 270, 77, 943, 219 |
| 5 | 685, 90, 77, 943, 73 |
| 137, 18, 77, 943, 73 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 137 x 18 x 77 x 943 x 73 = 588207914910
Therefore, the lowest common multiple of 685,810,231,943,657 is 588207914910.
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 810 x 231 x 943 x 657 = 79408068512850
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
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
231 : 1, 3, 7, 11, 21, 33, 77, 231
943 : 1, 23, 41, 943
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,810,231,943,657, is 1.
Now, the common factors can be found like this.
685:5x 137
810:2x 3x 3x 3x 3x 5
231:3x 7x 11
943:23x 41
657:3x 3x 73
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 5 = 135
Therefore, the value for common factors is 135.
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 = 79408068512850/(1x135)
LCM = 79408068512850/135
LCM = 588207914910
Thus, we can understand that the LCM of 685,810,231,943,657 is 588207914910.
