Given numbers are 682,468,187,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 682,468,187,705 is 637554060.
Find LCM of 682,468,187,705 with Prime Factorization
2 | 682, 468, 187, 705 |
3 | 341, 234, 187, 705 |
11 | 341, 78, 187, 235 |
31, 78, 17, 235 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 31 x 78 x 17 x 235 = 637554060
Therefore, the lowest common multiple of 682,468,187,705 is 637554060.
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.
682 x 468 x 187 x 705 = 42078567960
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
187 : 1, 11, 17, 187
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,468,187,705, is 1.
Now, the common factors can be found like this.
682:2x 11x 31
468:2x 2x 3x 3x 13
187:11x 17
705:3x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 42078567960/(1x66)
LCM = 42078567960/66
LCM = 637554060
Thus, we can understand that the LCM of 682,468,187,705 is 637554060.
