Given numbers are 990,454,625,454
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 990,454,625,454 is 28091250.
Find LCM of 990,454,625,454 with Prime Factorization
2 | 990, 454, 625, 454 |
5 | 495, 227, 625, 227 |
227 | 99, 227, 125, 227 |
99, 1, 125, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 227 x 99 x 1 x 125 x 1 = 28091250
Therefore, the lowest common multiple of 990,454,625,454 is 28091250.
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.
990 x 454 x 625 x 454 = 127534275000
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.
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
454 : 1, 2, 227, 454
625 : 1, 5, 25, 125, 625
454 : 1, 2, 227, 454
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,454,625,454, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
454:2x 227
625:5x 5x 5x 5
454:2x 227
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 5x 227 = 4540
Therefore, the value for common factors is 4540.
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 = 127534275000/(1x4540)
LCM = 127534275000/4540
LCM = 28091250
Thus, we can understand that the LCM of 990,454,625,454 is 28091250.
