Given numbers are 687,693,838,603,922
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,693,838,603,922 is 4107603012282.
Find LCM of 687,693,838,603,922 with Prime Factorization
| 2 | 687, 693, 838, 603, 922 |
| 3 | 687, 693, 419, 603, 461 |
| 3 | 229, 231, 419, 201, 461 |
| 229, 77, 419, 67, 461 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 229 x 77 x 419 x 67 x 461 = 4107603012282
Therefore, the lowest common multiple of 687,693,838,603,922 is 4107603012282.
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.
687 x 693 x 838 x 603 x 922 = 221810562663228
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.
687 : 1, 3, 229, 687
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
838 : 1, 2, 419, 838
603 : 1, 3, 9, 67, 201, 603
922 : 1, 2, 461, 922
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,693,838,603,922, is 1.
Now, the common factors can be found like this.
687:3x 229
693:3x 3x 7x 11
838:2x 419
603:3x 3x 67
922:2x 461
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 221810562663228/(1x54)
LCM = 221810562663228/54
LCM = 4107603012282
Thus, we can understand that the LCM of 687,693,838,603,922 is 4107603012282.
