Given numbers are 7,678,981,363
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,678,981,363 is 187784982.
Find LCM of 7,678,981,363 with Prime Factorization
| 3 | 7, 678, 981, 363 |
| 7, 226, 327, 121 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 226 x 327 x 121 = 187784982
Therefore, the lowest common multiple of 7,678,981,363 is 187784982.
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 981 x 363 = 1690064838
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
981 : 1, 3, 9, 109, 327, 981
363 : 1, 3, 11, 33, 121, 363
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,678,981,363, is 1.
Now, the common factors can be found like this.
7:7
678:2x 3x 113
981:3x 3x 109
363:3x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 1690064838/(1x9)
LCM = 1690064838/9
LCM = 187784982
Thus, we can understand that the LCM of 7,678,981,363 is 187784982.
