Find LCM of 561,924,831,716,831 with Prime Factorization
| 2 | 561, 924, 831, 716, 831 |
| 2 | 561, 462, 831, 358, 831 |
| 3 | 561, 231, 831, 179, 831 |
| 11 | 187, 77, 277, 179, 277 |
| 277 | 17, 7, 277, 179, 277 |
| 17, 7, 1, 179, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 277 x 17 x 7 x 1 x 179 x 1 = 778849764
Therefore, the lowest common multiple of 561,924,831,716,831 is 778849764.
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.
561 x 924 x 831 x 716 x 831 = 256300764938064
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
831 : 1, 3, 277, 831
716 : 1, 2, 4, 179, 358, 716
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,924,831,716,831, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
924:2x 2x 3x 7x 11
831:3x 277
716:2x 2x 179
831:3x 277
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 3x 3x 3x 11x 277 = 329076
Therefore, the value for common factors is 329076.
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 = 256300764938064/(1x329076)
LCM = 256300764938064/329076
LCM = 778849764
Thus, we can understand that the LCM of 561,924,831,716,831 is 778849764.
