Given numbers are 855,655,475,917
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,655,475,917 is 3920175.
Find LCM of 855,655,475,917 with Prime Factorization
| 5 | 855, 655, 475, 917 |
| 19 | 171, 131, 95, 917 |
| 131 | 9, 131, 5, 917 |
| 9, 1, 5, 7 |
Multiply the prime numbers at the bottom and the left side.
5 x 19 x 131 x 9 x 1 x 5 x 7 = 3920175
Therefore, the lowest common multiple of 855,655,475,917 is 3920175.
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.
855 x 655 x 475 x 917 = 243932889375
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
655 : 1, 5, 131, 655
475 : 1, 5, 19, 25, 95, 475
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,655,475,917, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
655:5x 131
475:5x 5x 19
917:7x 131
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 19x 131 = 62225
Therefore, the value for common factors is 62225.
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 = 243932889375/(1x62225)
LCM = 243932889375/62225
LCM = 3920175
Thus, we can understand that the LCM of 855,655,475,917 is 3920175.
