Find LCM of 196,831,794,390,520 with Prime Factorization
| 2 | 196, 831, 794, 390, 520 |
| 2 | 98, 831, 397, 195, 260 |
| 3 | 49, 831, 397, 195, 130 |
| 5 | 49, 277, 397, 65, 130 |
| 13 | 49, 277, 397, 13, 26 |
| 49, 277, 397, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 49 x 277 x 397 x 1 x 2 = 8406030360
Therefore, the lowest common multiple of 196,831,794,390,520 is 8406030360.
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.
196 x 831 x 794 x 390 x 520 = 26226814723200
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.
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
831 : 1, 3, 277, 831
794 : 1, 2, 397, 794
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 196,831,794,390,520, is 1.
Now, the common factors can be found like this.
196:2x 2x 7x 7
831:3x 277
794:2x 397
390:2x 3x 5x 13
520:2x 2x 2x 5x 13
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 5x 13 = 3120
Therefore, the value for common factors is 3120.
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 = 26226814723200/(1x3120)
LCM = 26226814723200/3120
LCM = 8406030360
Thus, we can understand that the LCM of 196,831,794,390,520 is 8406030360.
