Find LCM of 783,427,705,972,382 with Prime Factorization
| 2 | 783, 427, 705, 972, 382 |
| 3 | 783, 427, 705, 486, 191 |
| 3 | 261, 427, 235, 162, 191 |
| 3 | 87, 427, 235, 54, 191 |
| 29, 427, 235, 18, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 29 x 427 x 235 x 18 x 191 = 540248248260
Therefore, the lowest common multiple of 783,427,705,972,382 is 540248248260.
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.
783 x 427 x 705 x 972 x 382 = 87520216218120
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
427 : 1, 7, 61, 427
705 : 1, 3, 5, 15, 47, 141, 235, 705
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
382 : 1, 2, 191, 382
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,427,705,972,382, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
427:7x 61
705:3x 5x 47
972:2x 2x 3x 3x 3x 3x 3
382:2x 191
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 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 87520216218120/(1x162)
LCM = 87520216218120/162
LCM = 540248248260
Thus, we can understand that the LCM of 783,427,705,972,382 is 540248248260.
