Find LCM of 840,348,892,783,432 with Prime Factorization
| 2 | 840, 348, 892, 783, 432 |
| 2 | 420, 174, 446, 783, 216 |
| 2 | 210, 87, 223, 783, 108 |
| 3 | 105, 87, 223, 783, 54 |
| 3 | 35, 29, 223, 261, 18 |
| 3 | 35, 29, 223, 87, 6 |
| 29 | 35, 29, 223, 29, 2 |
| 35, 1, 223, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 29 x 35 x 1 x 223 x 1 x 2 = 97781040
Therefore, the lowest common multiple of 840,348,892,783,432 is 97781040.
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 348 x 892 x 783 x 432 = 88200062576640
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
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
892 : 1, 2, 4, 223, 446, 892
783 : 1, 3, 9, 27, 29, 87, 261, 783
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,348,892,783,432, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
348:2x 2x 3x 29
892:2x 2x 223
783:3x 3x 3x 29
432:2x 2x 2x 2x 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 2x 2x 3x 3x 3x 3x 3x 29 = 902016
Therefore, the value for common factors is 902016.
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 = 88200062576640/(1x902016)
LCM = 88200062576640/902016
LCM = 97781040
Thus, we can understand that the LCM of 840,348,892,783,432 is 97781040.
