Find LCM of 213,745,840,648,554 with Prime Factorization
| 2 | 213, 745, 840, 648, 554 |
| 2 | 213, 745, 420, 324, 277 |
| 2 | 213, 745, 210, 162, 277 |
| 3 | 213, 745, 105, 81, 277 |
| 5 | 71, 745, 35, 27, 277 |
| 71, 149, 7, 27, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 71 x 149 x 7 x 27 x 277 = 66461086440
Therefore, the lowest common multiple of 213,745,840,648,554 is 66461086440.
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.
213 x 745 x 840 x 648 x 554 = 47851982236800
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.
213 : 1, 3, 71, 213
745 : 1, 5, 149, 745
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,745,840,648,554, is 1.
Now, the common factors can be found like this.
213:3x 71
745:5x 149
840:2x 2x 2x 3x 5x 7
648:2x 2x 2x 3x 3x 3x 3
554:2x 277
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 5 = 720
Therefore, the value for common factors is 720.
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 = 47851982236800/(1x720)
LCM = 47851982236800/720
LCM = 66461086440
Thus, we can understand that the LCM of 213,745,840,648,554 is 66461086440.
