Given numbers are 409,861,598,861,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 409,861,598,861,685 is 144250794870.
Find LCM of 409,861,598,861,685 with Prime Factorization
| 3 | 409, 861, 598, 861, 685 |
| 7 | 409, 287, 598, 287, 685 |
| 41 | 409, 41, 598, 41, 685 |
| 409, 1, 598, 1, 685 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 41 x 409 x 1 x 598 x 1 x 685 = 144250794870
Therefore, the lowest common multiple of 409,861,598,861,685 is 144250794870.
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.
409 x 861 x 598 x 861 x 685 = 124199934383070
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.
409 : 1, 409
861 : 1, 3, 7, 21, 41, 123, 287, 861
598 : 1, 2, 13, 23, 26, 46, 299, 598
861 : 1, 3, 7, 21, 41, 123, 287, 861
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,861,598,861,685, is 1.
Now, the common factors can be found like this.
409:409
861:3x 7x 41
598:2x 13x 23
861:3x 7x 41
685:5x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 41 = 861
Therefore, the value for common factors is 861.
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 = 124199934383070/(1x861)
LCM = 124199934383070/861
LCM = 144250794870
Thus, we can understand that the LCM of 409,861,598,861,685 is 144250794870.
