Given numbers are 979,861,451,110,146
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,861,451,110,146 is 615330870.
Find LCM of 979,861,451,110,146 with Prime Factorization
| 2 | 979, 861, 451, 110, 146 |
| 11 | 979, 861, 451, 55, 73 |
| 41 | 89, 861, 41, 5, 73 |
| 89, 21, 1, 5, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 41 x 89 x 21 x 1 x 5 x 73 = 615330870
Therefore, the lowest common multiple of 979,861,451,110,146 is 615330870.
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.
979 x 861 x 451 x 110 x 146 = 6105312892140
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.
979 : 1, 11, 89, 979
861 : 1, 3, 7, 21, 41, 123, 287, 861
451 : 1, 11, 41, 451
110 : 1, 2, 5, 10, 11, 22, 55, 110
146 : 1, 2, 73, 146
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,861,451,110,146, is 1.
Now, the common factors can be found like this.
979:11x 89
861:3x 7x 41
451:11x 41
110:2x 5x 11
146:2x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11x 41 = 9922
Therefore, the value for common factors is 9922.
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 = 6105312892140/(1x9922)
LCM = 6105312892140/9922
LCM = 615330870
Thus, we can understand that the LCM of 979,861,451,110,146 is 615330870.
