Given numbers are 655,437,209,605,415
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,437,209,605,415 is 2874658105.
Find LCM of 655,437,209,605,415 with Prime Factorization
| 5 | 655, 437, 209, 605, 415 |
| 11 | 131, 437, 209, 121, 83 |
| 19 | 131, 437, 19, 11, 83 |
| 131, 23, 1, 11, 83 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 19 x 131 x 23 x 1 x 11 x 83 = 2874658105
Therefore, the lowest common multiple of 655,437,209,605,415 is 2874658105.
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.
655 x 437 x 209 x 605 x 415 = 15020088598625
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.
655 : 1, 5, 131, 655
437 : 1, 19, 23, 437
209 : 1, 11, 19, 209
605 : 1, 5, 11, 55, 121, 605
415 : 1, 5, 83, 415
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,437,209,605,415, is 1.
Now, the common factors can be found like this.
655:5x 131
437:19x 23
209:11x 19
605:5x 11x 11
415:5x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 11x 19 = 5225
Therefore, the value for common factors is 5225.
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 = 15020088598625/(1x5225)
LCM = 15020088598625/5225
LCM = 2874658105
Thus, we can understand that the LCM of 655,437,209,605,415 is 2874658105.
