Find LCM of 259,984,738,840 with Prime Factorization
| 2 | 259, 984, 738, 840 |
| 2 | 259, 492, 369, 420 |
| 2 | 259, 246, 369, 210 |
| 3 | 259, 123, 369, 105 |
| 7 | 259, 41, 123, 35 |
| 41 | 37, 41, 123, 5 |
| 37, 1, 3, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 41 x 37 x 1 x 3 x 5 = 3822840
Therefore, the lowest common multiple of 259,984,738,840 is 3822840.
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.
259 x 984 x 738 x 840 = 157990331520
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.
259 : 1, 7, 37, 259
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 259,984,738,840, is 1.
Now, the common factors can be found like this.
259:7x 37
984:2x 2x 2x 3x 41
738:2x 3x 3x 41
840:2x 2x 2x 3x 5x 7
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 3x 3x 7x 41 = 41328
Therefore, the value for common factors is 41328.
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 = 157990331520/(1x41328)
LCM = 157990331520/41328
LCM = 3822840
Thus, we can understand that the LCM of 259,984,738,840 is 3822840.
