Find LCM of 649,432,620,469,243 with Prime Factorization
| 2 | 649, 432, 620, 469, 243 |
| 2 | 649, 216, 310, 469, 243 |
| 3 | 649, 108, 155, 469, 243 |
| 3 | 649, 36, 155, 469, 81 |
| 3 | 649, 12, 155, 469, 27 |
| 649, 4, 155, 469, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 649 x 4 x 155 x 469 x 9 = 183432165840
Therefore, the lowest common multiple of 649,432,620,469,243 is 183432165840.
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.
649 x 432 x 620 x 469 x 243 = 19810673910720
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.
649 : 1, 11, 59, 649
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
469 : 1, 7, 67, 469
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,432,620,469,243, is 1.
Now, the common factors can be found like this.
649:11x 59
432:2x 2x 2x 2x 3x 3x 3
620:2x 2x 5x 31
469:7x 67
243:3x 3x 3x 3x 3
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 3 = 108
Therefore, the value for common factors is 108.
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 = 19810673910720/(1x108)
LCM = 19810673910720/108
LCM = 183432165840
Thus, we can understand that the LCM of 649,432,620,469,243 is 183432165840.
