Given numbers are 190,103,921,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 190,103,921,309 is 18023970.
Find LCM of 190,103,921,309 with Prime Factorization
| 3 | 190, 103, 921, 309 |
| 103 | 190, 103, 307, 103 |
| 190, 1, 307, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 103 x 190 x 1 x 307 x 1 = 18023970
Therefore, the lowest common multiple of 190,103,921,309 is 18023970.
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.
190 x 103 x 921 x 309 = 5569406730
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.
190 : 1, 2, 5, 10, 19, 38, 95, 190
103 : 1, 103
921 : 1, 3, 307, 921
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 190,103,921,309, is 1.
Now, the common factors can be found like this.
190:2x 5x 19
103:103
921:3x 307
309:3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 103 = 309
Therefore, the value for common factors is 309.
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 = 5569406730/(1x309)
LCM = 5569406730/309
LCM = 18023970
Thus, we can understand that the LCM of 190,103,921,309 is 18023970.
