Find LCM of 405,666,364,546,625 with Prime Factorization
| 2 | 405, 666, 364, 546, 625 |
| 3 | 405, 333, 182, 273, 625 |
| 3 | 135, 111, 182, 91, 625 |
| 5 | 45, 37, 182, 91, 625 |
| 7 | 9, 37, 182, 91, 125 |
| 13 | 9, 37, 26, 13, 125 |
| 9, 37, 2, 1, 125 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 13 x 9 x 37 x 2 x 1 x 125 = 681817500
Therefore, the lowest common multiple of 405,666,364,546,625 is 681817500.
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 666 x 364 x 546 x 625 = 33504511950000
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
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
625 : 1, 5, 25, 125, 625
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,666,364,546,625, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
666:2x 3x 3x 37
364:2x 2x 7x 13
546:2x 3x 7x 13
625:5x 5x 5x 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 5x 7x 13 = 49140
Therefore, the value for common factors is 49140.
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 = 33504511950000/(1x49140)
LCM = 33504511950000/49140
LCM = 681817500
Thus, we can understand that the LCM of 405,666,364,546,625 is 681817500.
