Find LCM of 405,625,789,918,764 with Prime Factorization
| 2 | 405, 625, 789, 918, 764 |
| 3 | 405, 625, 789, 459, 382 |
| 3 | 135, 625, 263, 153, 382 |
| 3 | 45, 625, 263, 51, 382 |
| 5 | 15, 625, 263, 17, 382 |
| 3, 125, 263, 17, 382 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 3 x 125 x 263 x 17 x 382 = 172927102500
Therefore, the lowest common multiple of 405,625,789,918,764 is 172927102500.
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.
405 x 625 x 789 x 918 x 764 = 140070953025000
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
625 : 1, 5, 25, 125, 625
789 : 1, 3, 263, 789
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
764 : 1, 2, 4, 191, 382, 764
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,625,789,918,764, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
625:5x 5x 5x 5
789:3x 263
918:2x 3x 3x 3x 17
764:2x 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 3x 5 = 810
Therefore, the value for common factors is 810.
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 = 140070953025000/(1x810)
LCM = 140070953025000/810
LCM = 172927102500
Thus, we can understand that the LCM of 405,625,789,918,764 is 172927102500.
