Given numbers are 509,981,874,486,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 509,981,874,486,978 is 1920656015946.
Find LCM of 509,981,874,486,978 with Prime Factorization
| 2 | 509, 981, 874, 486, 978 |
| 3 | 509, 981, 437, 243, 489 |
| 3 | 509, 327, 437, 81, 163 |
| 509, 109, 437, 27, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 509 x 109 x 437 x 27 x 163 = 1920656015946
Therefore, the lowest common multiple of 509,981,874,486,978 is 1920656015946.
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 981 x 874 x 486 x 978 = 207430849722168
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
981 : 1, 3, 9, 109, 327, 981
874 : 1, 2, 19, 23, 38, 46, 437, 874
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 509,981,874,486,978, is 1.
Now, the common factors can be found like this.
509:509
981:3x 3x 109
874:2x 19x 23
486:2x 3x 3x 3x 3x 3
978:2x 3x 163
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 3 = 108
Therefore, the value for common factors is 108.
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 = 207430849722168/(1x108)
LCM = 207430849722168/108
LCM = 1920656015946
Thus, we can understand that the LCM of 509,981,874,486,978 is 1920656015946.
