Given numbers are 305,806,347,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 305,806,347,915 is 255909030.
Find LCM of 305,806,347,915 with Prime Factorization
| 5 | 305, 806, 347, 915 |
| 61 | 61, 806, 347, 183 |
| 1, 806, 347, 3 |
Multiply the prime numbers at the bottom and the left side.
5 x 61 x 1 x 806 x 347 x 3 = 255909030
Therefore, the lowest common multiple of 305,806,347,915 is 255909030.
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.
305 x 806 x 347 x 915 = 78052254150
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.
305 : 1, 5, 61, 305
806 : 1, 2, 13, 26, 31, 62, 403, 806
347 : 1, 347
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,806,347,915, is 1.
Now, the common factors can be found like this.
305:5x 61
806:2x 13x 31
347:347
915:3x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 61 = 305
Therefore, the value for common factors is 305.
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 = 78052254150/(1x305)
LCM = 78052254150/305
LCM = 255909030
Thus, we can understand that the LCM of 305,806,347,915 is 255909030.
