Given numbers are 190,931,786,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 190,931,786,494 is 47564790.
Find LCM of 190,931,786,494 with Prime Factorization
| 2 | 190, 931, 786, 494 |
| 19 | 95, 931, 393, 247 |
| 5, 49, 393, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 5 x 49 x 393 x 13 = 47564790
Therefore, the lowest common multiple of 190,931,786,494 is 47564790.
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 931 x 786 x 494 = 68683556760
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
931 : 1, 7, 19, 49, 133, 931
786 : 1, 2, 3, 6, 131, 262, 393, 786
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 190,931,786,494, is 1.
Now, the common factors can be found like this.
190:2x 5x 19
931:7x 7x 19
786:2x 3x 131
494:2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 19x 19 = 1444
Therefore, the value for common factors is 1444.
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 = 68683556760/(1x1444)
LCM = 68683556760/1444
LCM = 47564790
Thus, we can understand that the LCM of 190,931,786,494 is 47564790.
