Given numbers are 315,834,255,417
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,834,255,417 is 1488690.
Find LCM of 315,834,255,417 with Prime Factorization
| 3 | 315, 834, 255, 417 |
| 5 | 105, 278, 85, 139 |
| 139 | 21, 278, 17, 139 |
| 21, 2, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 139 x 21 x 2 x 17 x 1 = 1488690
Therefore, the lowest common multiple of 315,834,255,417 is 1488690.
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.
315 x 834 x 255 x 417 = 27935267850
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
834 : 1, 2, 3, 6, 139, 278, 417, 834
255 : 1, 3, 5, 15, 17, 51, 85, 255
417 : 1, 3, 139, 417
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,834,255,417, is 3.
Now, the common factors can be found like this.
315:3x 3x 5x 7
834:2x 3x 139
255:3x 5x 17
417:3x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 139 = 6255
Therefore, the value for common factors is 6255.
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 = 27935267850/(3x6255)
LCM = 27935267850/18765
LCM = 1488690
Thus, we can understand that the LCM of 315,834,255,417 is 1488690.
