Given numbers are 315,431,869,465,775
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,431,869,465,775 is 18286866675.
Find LCM of 315,431,869,465,775 with Prime Factorization
| 3 | 315, 431, 869, 465, 775 |
| 5 | 105, 431, 869, 155, 775 |
| 31 | 21, 431, 869, 31, 155 |
| 21, 431, 869, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 31 x 21 x 431 x 869 x 1 x 5 = 18286866675
Therefore, the lowest common multiple of 315,431,869,465,775 is 18286866675.
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 431 x 869 x 465 x 775 = 42516965019375
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
431 : 1, 431
869 : 1, 11, 79, 869
465 : 1, 3, 5, 15, 31, 93, 155, 465
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,431,869,465,775, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
431:431
869:11x 79
465:3x 5x 31
775:5x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 31 = 2325
Therefore, the value for common factors is 2325.
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 = 42516965019375/(1x2325)
LCM = 42516965019375/2325
LCM = 18286866675
Thus, we can understand that the LCM of 315,431,869,465,775 is 18286866675.
