Given numbers are 682,978,120,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 682,978,120,434 is 46689720.
Find LCM of 682,978,120,434 with Prime Factorization
| 2 | 682, 978, 120, 434 |
| 3 | 341, 489, 60, 217 |
| 31 | 341, 163, 20, 217 |
| 11, 163, 20, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 31 x 11 x 163 x 20 x 7 = 46689720
Therefore, the lowest common multiple of 682,978,120,434 is 46689720.
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 978 x 120 x 434 = 34737151680
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
978 : 1, 2, 3, 6, 163, 326, 489, 978
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
434 : 1, 2, 7, 14, 31, 62, 217, 434
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,978,120,434, is 2.
Now, the common factors can be found like this.
682:2x 11x 31
978:2x 3x 163
120:2x 2x 2x 3x 5
434:2x 7x 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 3x 31 = 372
Therefore, the value for common factors is 372.
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 = 34737151680/(2x372)
LCM = 34737151680/744
LCM = 46689720
Thus, we can understand that the LCM of 682,978,120,434 is 46689720.
