The LCM of 190,551,644,812 is 1774220.
Find LCM of 190,551,644,812 with Prime Factorization
| 2 | 190, 551, 644, 812 |
| 2 | 95, 551, 322, 406 |
| 7 | 95, 551, 161, 203 |
| 19 | 95, 551, 23, 29 |
| 29 | 5, 29, 23, 29 |
| 5, 1, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 19 x 29 x 5 x 1 x 23 x 1 = 1774220
Therefore, the lowest common multiple of 190,551,644,812 is 1774220.
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.
190 x 551 x 644 x 812 = 54745332320
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.
190 : 1, 2, 5, 10, 19, 38, 95, 190
551 : 1, 19, 29, 551
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 190,551,644,812, is 1.
Now, the common factors can be found like this.
190:2x 5x 19
551:19x 29
644:2x 2x 7x 23
812:2x 2x 7x 29
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 7x 19x 29 = 30856
Therefore, the value for common factors is 30856.
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 = 54745332320/(1x30856)
LCM = 54745332320/30856
LCM = 1774220
Thus, we can understand that the LCM of 190,551,644,812 is 1774220.
