Find LCM of 612,838,445,783,419 with Prime Factorization
| 2 | 612, 838, 445, 783, 419 |
| 3 | 306, 419, 445, 783, 419 |
| 3 | 102, 419, 445, 261, 419 |
| 419 | 34, 419, 445, 87, 419 |
| 34, 1, 445, 87, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 419 x 34 x 1 x 445 x 87 x 1 = 9927610020
Therefore, the lowest common multiple of 612,838,445,783,419 is 9927610020.
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.
612 x 838 x 445 x 783 x 419 = 74874034770840
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.
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
838 : 1, 2, 419, 838
445 : 1, 5, 89, 445
783 : 1, 3, 9, 27, 29, 87, 261, 783
419 : 1, 419
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,838,445,783,419, is 1.
Now, the common factors can be found like this.
612:2x 2x 3x 3x 17
838:2x 419
445:5x 89
783:3x 3x 3x 29
419:419
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 419 = 7542
Therefore, the value for common factors is 7542.
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 = 74874034770840/(1x7542)
LCM = 74874034770840/7542
LCM = 9927610020
Thus, we can understand that the LCM of 612,838,445,783,419 is 9927610020.
