Given numbers are 509,202,990,253,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 509,202,990,253,989 is 50335065990.
Find LCM of 509,202,990,253,989 with Prime Factorization
| 2 | 509, 202, 990, 253, 989 |
| 11 | 509, 101, 495, 253, 989 |
| 23 | 509, 101, 45, 23, 989 |
| 509, 101, 45, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 23 x 509 x 101 x 45 x 1 x 43 = 50335065990
Therefore, the lowest common multiple of 509,202,990,253,989 is 50335065990.
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.
509 x 202 x 990 x 253 x 989 = 25469543390940
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.
509 : 1, 509
202 : 1, 2, 101, 202
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
253 : 1, 11, 23, 253
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 509,202,990,253,989, is 1.
Now, the common factors can be found like this.
509:509
202:2x 101
990:2x 3x 3x 5x 11
253:11x 23
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 23 = 506
Therefore, the value for common factors is 506.
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 = 25469543390940/(1x506)
LCM = 25469543390940/506
LCM = 50335065990
Thus, we can understand that the LCM of 509,202,990,253,989 is 50335065990.
