Given numbers are 647,409,650,650,810
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,409,650,650,810 is 13932400950.
Find LCM of 647,409,650,650,810 with Prime Factorization
| 2 | 647, 409, 650, 650, 810 |
| 5 | 647, 409, 325, 325, 405 |
| 5 | 647, 409, 65, 65, 81 |
| 13 | 647, 409, 13, 13, 81 |
| 647, 409, 1, 1, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 13 x 647 x 409 x 1 x 1 x 81 = 13932400950
Therefore, the lowest common multiple of 647,409,650,650,810 is 13932400950.
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.
647 x 409 x 650 x 650 x 810 = 90560606175000
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.
647 : 1, 647
409 : 1, 409
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,409,650,650,810, is 1.
Now, the common factors can be found like this.
647:647
409:409
650:2x 5x 5x 13
650:2x 5x 5x 13
810:2x 3x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 5x 5x 13 = 6500
Therefore, the value for common factors is 6500.
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 = 90560606175000/(1x6500)
LCM = 90560606175000/6500
LCM = 13932400950
Thus, we can understand that the LCM of 647,409,650,650,810 is 13932400950.
