Find LCM of 843,784,936,910,231 with Prime Factorization
| 2 | 843, 784, 936, 910, 231 |
| 2 | 843, 392, 468, 455, 231 |
| 2 | 843, 196, 234, 455, 231 |
| 3 | 843, 98, 117, 455, 231 |
| 7 | 281, 98, 39, 455, 77 |
| 13 | 281, 14, 39, 65, 11 |
| 281, 14, 3, 5, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 13 x 281 x 14 x 3 x 5 x 11 = 1417656240
Therefore, the lowest common multiple of 843,784,936,910,231 is 1417656240.
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.
843 x 784 x 936 x 910 x 231 = 130038771582720
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.
843 : 1, 3, 281, 843
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,784,936,910,231, is 1.
Now, the common factors can be found like this.
843:3x 281
784:2x 2x 2x 2x 7x 7
936:2x 2x 2x 3x 3x 13
910:2x 5x 7x 13
231:3x 7x 11
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 7x 13 = 91728
Therefore, the value for common factors is 91728.
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 = 130038771582720/(1x91728)
LCM = 130038771582720/91728
LCM = 1417656240
Thus, we can understand that the LCM of 843,784,936,910,231 is 1417656240.
