Find LCM of 207,485,643,180,252 with Prime Factorization
| 2 | 207, 485, 643, 180, 252 |
| 2 | 207, 485, 643, 90, 126 |
| 3 | 207, 485, 643, 45, 63 |
| 3 | 69, 485, 643, 15, 21 |
| 5 | 23, 485, 643, 5, 7 |
| 23, 97, 643, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 23 x 97 x 643 x 1 x 7 = 1807511580
Therefore, the lowest common multiple of 207,485,643,180,252 is 1807511580.
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.
207 x 485 x 643 x 180 x 252 = 2928168759600
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.
207 : 1, 3, 9, 23, 69, 207
485 : 1, 5, 97, 485
643 : 1, 643
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,485,643,180,252, is 1.
Now, the common factors can be found like this.
207:3x 3x 23
485:5x 97
643:643
180:2x 2x 3x 3x 5
252:2x 2x 3x 3x 7
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 5 = 1620
Therefore, the value for common factors is 1620.
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 = 2928168759600/(1x1620)
LCM = 2928168759600/1620
LCM = 1807511580
Thus, we can understand that the LCM of 207,485,643,180,252 is 1807511580.
