Find LCM of 308,834,958,519,420 with Prime Factorization
| 2 | 308, 834, 958, 519, 420 |
| 2 | 154, 417, 479, 519, 210 |
| 3 | 77, 417, 479, 519, 105 |
| 7 | 77, 139, 479, 173, 35 |
| 11, 139, 479, 173, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 139 x 479 x 173 x 5 = 53215530060
Therefore, the lowest common multiple of 308,834,958,519,420 is 53215530060.
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.
308 x 834 x 958 x 519 x 420 = 53641254300480
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
834 : 1, 2, 3, 6, 139, 278, 417, 834
958 : 1, 2, 479, 958
519 : 1, 3, 173, 519
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,834,958,519,420, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
834:2x 3x 139
958:2x 479
519:3x 173
420:2x 2x 3x 5x 7
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 3x 7 = 1008
Therefore, the value for common factors is 1008.
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 = 53641254300480/(1x1008)
LCM = 53641254300480/1008
LCM = 53215530060
Thus, we can understand that the LCM of 308,834,958,519,420 is 53215530060.
