Given numbers are 505,404,556,788,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 505,404,556,788,648 is 8960812920.
Find LCM of 505,404,556,788,648 with Prime Factorization
| 2 | 505, 404, 556, 788, 648 |
| 2 | 505, 202, 278, 394, 324 |
| 101 | 505, 101, 139, 197, 162 |
| 5, 1, 139, 197, 162 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 101 x 5 x 1 x 139 x 197 x 162 = 8960812920
Therefore, the lowest common multiple of 505,404,556,788,648 is 8960812920.
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.
505 x 404 x 556 x 788 x 648 = 57922694714880
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.
505 : 1, 5, 101, 505
404 : 1, 2, 4, 101, 202, 404
556 : 1, 2, 4, 139, 278, 556
788 : 1, 2, 4, 197, 394, 788
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,404,556,788,648, is 1.
Now, the common factors can be found like this.
505:5x 101
404:2x 2x 101
556:2x 2x 139
788:2x 2x 197
648:2x 2x 2x 3x 3x 3x 3
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 2x 2x 2x 101 = 6464
Therefore, the value for common factors is 6464.
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 = 57922694714880/(1x6464)
LCM = 57922694714880/6464
LCM = 8960812920
Thus, we can understand that the LCM of 505,404,556,788,648 is 8960812920.
