Given numbers are 682,489,570,992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 682,489,570,992 is 506916960.
Find LCM of 682,489,570,992 with Prime Factorization
| 2 | 682, 489, 570, 992 |
| 3 | 341, 489, 285, 496 |
| 31 | 341, 163, 95, 496 |
| 11, 163, 95, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 31 x 11 x 163 x 95 x 16 = 506916960
Therefore, the lowest common multiple of 682,489,570,992 is 506916960.
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 489 x 570 x 992 = 188573109120
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
489 : 1, 3, 163, 489
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,489,570,992, is 1.
Now, the common factors can be found like this.
682:2x 11x 31
489:3x 163
570:2x 3x 5x 19
992:2x 2x 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 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 = 188573109120/(1x372)
LCM = 188573109120/372
LCM = 506916960
Thus, we can understand that the LCM of 682,489,570,992 is 506916960.
