Find LCM of 191,120,987,392,848 with Prime Factorization
| 2 | 191, 120, 987, 392, 848 |
| 2 | 191, 60, 987, 196, 424 |
| 2 | 191, 30, 987, 98, 212 |
| 3 | 191, 15, 987, 49, 106 |
| 7 | 191, 5, 329, 49, 106 |
| 191, 5, 47, 7, 106 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 191 x 5 x 47 x 7 x 106 = 5595184560
Therefore, the lowest common multiple of 191,120,987,392,848 is 5595184560.
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.
191 x 120 x 987 x 392 x 848 = 7519928048640
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.
191 : 1, 191
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
987 : 1, 3, 7, 21, 47, 141, 329, 987
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,120,987,392,848, is 1.
Now, the common factors can be found like this.
191:191
120:2x 2x 2x 3x 5
987:3x 7x 47
392:2x 2x 2x 7x 7
848:2x 2x 2x 2x 53
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 3x 7 = 1344
Therefore, the value for common factors is 1344.
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 = 7519928048640/(1x1344)
LCM = 7519928048640/1344
LCM = 5595184560
Thus, we can understand that the LCM of 191,120,987,392,848 is 5595184560.
