The LCM of 540,454,195,810 is 4780620.
Find LCM of 540,454,195,810 with Prime Factorization
| 2 | 540, 454, 195, 810 |
| 3 | 270, 227, 195, 405 |
| 3 | 90, 227, 65, 135 |
| 3 | 30, 227, 65, 45 |
| 5 | 10, 227, 65, 15 |
| 2, 227, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 2 x 227 x 13 x 3 = 4780620
Therefore, the lowest common multiple of 540,454,195,810 is 4780620.
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.
540 x 454 x 195 x 810 = 38723022000
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.
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
454 : 1, 2, 227, 454
195 : 1, 3, 5, 13, 15, 39, 65, 195
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 540,454,195,810, is 1.
Now, the common factors can be found like this.
540:2x 2x 3x 3x 3x 5
454:2x 227
195:3x 5x 13
810:2x 3x 3x 3x 3x 5
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 3x 3x 3x 3x 5x 5 = 8100
Therefore, the value for common factors is 8100.
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 = 38723022000/(1x8100)
LCM = 38723022000/8100
LCM = 4780620
Thus, we can understand that the LCM of 540,454,195,810 is 4780620.
