Find LCM of 475,928,642,428,725 with Prime Factorization
2 | 475, 928, 642, 428, 725 |
2 | 475, 464, 321, 214, 725 |
5 | 475, 232, 321, 107, 725 |
5 | 95, 232, 321, 107, 145 |
29 | 19, 232, 321, 107, 29 |
107 | 19, 8, 321, 107, 1 |
19, 8, 3, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 29 x 107 x 19 x 8 x 3 x 1 x 1 = 141496800
Therefore, the lowest common multiple of 475,928,642,428,725 is 141496800.
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.
475 x 928 x 642 x 428 x 725 = 87812914080000
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.
475 : 1, 5, 19, 25, 95, 475
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
642 : 1, 2, 3, 6, 107, 214, 321, 642
428 : 1, 2, 4, 107, 214, 428
725 : 1, 5, 25, 29, 145, 725
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 475,928,642,428,725, is 1.
Now, the common factors can be found like this.
475:5x 5x 19
928:2x 2x 2x 2x 2x 29
642:2x 3x 107
428:2x 2x 107
725:5x 5x 29
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 5x 5x 29x 107 = 620600
Therefore, the value for common factors is 620600.
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 = 87812914080000/(1x620600)
LCM = 87812914080000/620600
LCM = 141496800
Thus, we can understand that the LCM of 475,928,642,428,725 is 141496800.
