Find LCM of 682,860,492,558,648 with Prime Factorization
| 2 | 682, 860, 492, 558, 648 |
| 2 | 341, 430, 246, 279, 324 |
| 3 | 341, 215, 123, 279, 162 |
| 3 | 341, 215, 41, 93, 54 |
| 31 | 341, 215, 41, 31, 18 |
| 11, 215, 41, 1, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 31 x 11 x 215 x 41 x 1 x 18 = 1947832920
Therefore, the lowest common multiple of 682,860,492,558,648 is 1947832920.
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 860 x 492 x 558 x 648 = 104341513858560
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
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,860,492,558,648, is 2.
Now, the common factors can be found like this.
682:2x 11x 31
860:2x 2x 5x 43
492:2x 2x 3x 41
558:2x 3x 3x 31
648:2x 2x 2x 3x 3x 3x 3
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 3x 3x 3x 31 = 26784
Therefore, the value for common factors is 26784.
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 = 104341513858560/(2x26784)
LCM = 104341513858560/53568
LCM = 1947832920
Thus, we can understand that the LCM of 682,860,492,558,648 is 1947832920.
