Given numbers are 328,610,298,728,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 328,610,298,728,861 is 4069327080.
Find LCM of 328,610,298,728,861 with Prime Factorization
| 2 | 328, 610, 298, 728, 861 |
| 2 | 164, 305, 149, 364, 861 |
| 2 | 82, 305, 149, 182, 861 |
| 7 | 41, 305, 149, 91, 861 |
| 41 | 41, 305, 149, 13, 123 |
| 1, 305, 149, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 41 x 1 x 305 x 149 x 13 x 3 = 4069327080
Therefore, the lowest common multiple of 328,610,298,728,861 is 4069327080.
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.
328 x 610 x 298 x 728 x 861 = 37372699902720
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.
328 : 1, 2, 4, 8, 41, 82, 164, 328
610 : 1, 2, 5, 10, 61, 122, 305, 610
298 : 1, 2, 149, 298
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,610,298,728,861, is 1.
Now, the common factors can be found like this.
328:2x 2x 2x 41
610:2x 5x 61
298:2x 149
728:2x 2x 2x 7x 13
861:3x 7x 41
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 2x 2x 2x 7x 41 = 9184
Therefore, the value for common factors is 9184.
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 = 37372699902720/(1x9184)
LCM = 37372699902720/9184
LCM = 4069327080
Thus, we can understand that the LCM of 328,610,298,728,861 is 4069327080.
