Given numbers are 861,741,605,244,248
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,741,605,244,248 is 1946421957480.
Find LCM of 861,741,605,244,248 with Prime Factorization
| 2 | 861, 741, 605, 244, 248 |
| 2 | 861, 741, 605, 122, 124 |
| 3 | 861, 741, 605, 61, 62 |
| 287, 247, 605, 61, 62 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 287 x 247 x 605 x 61 x 62 = 1946421957480
Therefore, the lowest common multiple of 861,741,605,244,248 is 1946421957480.
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.
861 x 741 x 605 x 244 x 248 = 23357063489760
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
741 : 1, 3, 13, 19, 39, 57, 247, 741
605 : 1, 5, 11, 55, 121, 605
244 : 1, 2, 4, 61, 122, 244
248 : 1, 2, 4, 8, 31, 62, 124, 248
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,741,605,244,248, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
741:3x 13x 19
605:5x 11x 11
244:2x 2x 61
248:2x 2x 2x 31
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 3 = 12
Therefore, the value for common factors is 12.
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 = 23357063489760/(1x12)
LCM = 23357063489760/12
LCM = 1946421957480
Thus, we can understand that the LCM of 861,741,605,244,248 is 1946421957480.
