Find LCM of 840,441,394,524,879 with Prime Factorization
| 2 | 840, 441, 394, 524, 879 |
| 2 | 420, 441, 197, 262, 879 |
| 3 | 210, 441, 197, 131, 879 |
| 7 | 70, 147, 197, 131, 293 |
| 10, 21, 197, 131, 293 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 10 x 21 x 197 x 131 x 293 = 133383995640
Therefore, the lowest common multiple of 840,441,394,524,879 is 133383995640.
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.
840 x 441 x 394 x 524 x 879 = 67225533802560
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.
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
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
394 : 1, 2, 197, 394
524 : 1, 2, 4, 131, 262, 524
879 : 1, 3, 293, 879
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,441,394,524,879, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
441:3x 3x 7x 7
394:2x 197
524:2x 2x 131
879:3x 293
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 3x 3x 7 = 504
Therefore, the value for common factors is 504.
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 = 67225533802560/(1x504)
LCM = 67225533802560/504
LCM = 133383995640
Thus, we can understand that the LCM of 840,441,394,524,879 is 133383995640.
