Find LCM of 812,561,768,522,887 with Prime Factorization
| 2 | 812, 561, 768, 522, 887 |
| 2 | 406, 561, 384, 261, 887 |
| 3 | 203, 561, 192, 261, 887 |
| 29 | 203, 187, 64, 87, 887 |
| 7, 187, 64, 3, 887 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 29 x 7 x 187 x 64 x 3 x 887 = 77578921728
Therefore, the lowest common multiple of 812,561,768,522,887 is 77578921728.
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.
812 x 561 x 768 x 522 x 887 = 161984788568064
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
561 : 1, 3, 11, 17, 33, 51, 187, 561
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
887 : 1, 887
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,561,768,522,887, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
561:3x 11x 17
768:2x 2x 2x 2x 2x 2x 2x 2x 3
522:2x 3x 3x 29
887:887
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 29 = 2088
Therefore, the value for common factors is 2088.
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 = 161984788568064/(1x2088)
LCM = 161984788568064/2088
LCM = 77578921728
Thus, we can understand that the LCM of 812,561,768,522,887 is 77578921728.
