Given numbers are 7,678,707,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,678,707,385 is 26364030.
Find LCM of 7,678,707,385 with Prime Factorization
| 7 | 7, 678, 707, 385 |
| 1, 678, 101, 55 |
Multiply the prime numbers at the bottom and the left side.
7 x 1 x 678 x 101 x 55 = 26364030
Therefore, the lowest common multiple of 7,678,707,385 is 26364030.
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.
7 x 678 x 707 x 385 = 1291837470
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.
7 : 1, 7
678 : 1, 2, 3, 6, 113, 226, 339, 678
707 : 1, 7, 101, 707
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,678,707,385, is 1.
Now, the common factors can be found like this.
7:7
678:2x 3x 113
707:7x 101
385:5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7 = 49
Therefore, the value for common factors is 49.
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 = 1291837470/(1x49)
LCM = 1291837470/49
LCM = 26364030
Thus, we can understand that the LCM of 7,678,707,385 is 26364030.
