Given numbers are 603,840,687,690,563
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 603,840,687,690,563 is 500664797640.
Find LCM of 603,840,687,690,563 with Prime Factorization
| 2 | 603, 840, 687, 690, 563 |
| 3 | 603, 420, 687, 345, 563 |
| 5 | 201, 140, 229, 115, 563 |
| 201, 28, 229, 23, 563 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 201 x 28 x 229 x 23 x 563 = 500664797640
Therefore, the lowest common multiple of 603,840,687,690,563 is 500664797640.
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.
603 x 840 x 687 x 690 x 563 = 135179495362800
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.
603 : 1, 3, 9, 67, 201, 603
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
687 : 1, 3, 229, 687
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
563 : 1, 563
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 603,840,687,690,563, is 1.
Now, the common factors can be found like this.
603:3x 3x 67
840:2x 2x 2x 3x 5x 7
687:3x 229
690:2x 3x 5x 23
563:563
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 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 135179495362800/(1x270)
LCM = 135179495362800/270
LCM = 500664797640
Thus, we can understand that the LCM of 603,840,687,690,563 is 500664797640.
