Given numbers are 758,738,278,498,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 758,738,278,498,921 is 990665046018.
Find LCM of 758,738,278,498,921 with Prime Factorization
| 2 | 758, 738, 278, 498, 921 |
| 3 | 379, 369, 139, 249, 921 |
| 379, 123, 139, 83, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 379 x 123 x 139 x 83 x 307 = 990665046018
Therefore, the lowest common multiple of 758,738,278,498,921 is 990665046018.
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.
758 x 738 x 278 x 498 x 921 = 71327883313296
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.
758 : 1, 2, 379, 758
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
278 : 1, 2, 139, 278
498 : 1, 2, 3, 6, 83, 166, 249, 498
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 758,738,278,498,921, is 1.
Now, the common factors can be found like this.
758:2x 379
738:2x 3x 3x 41
278:2x 139
498:2x 3x 83
921:3x 307
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 71327883313296/(1x72)
LCM = 71327883313296/72
LCM = 990665046018
Thus, we can understand that the LCM of 758,738,278,498,921 is 990665046018.
