Given numbers are 920,278,809,741,513
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,278,809,741,513 is 689940861480.
Find LCM of 920,278,809,741,513 with Prime Factorization
| 2 | 920, 278, 809, 741, 513 |
| 3 | 460, 139, 809, 741, 513 |
| 19 | 460, 139, 809, 247, 171 |
| 460, 139, 809, 13, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 460 x 139 x 809 x 13 x 9 = 689940861480
Therefore, the lowest common multiple of 920,278,809,741,513 is 689940861480.
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.
920 x 278 x 809 x 741 x 513 = 78653258208720
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
278 : 1, 2, 139, 278
809 : 1, 809
741 : 1, 3, 13, 19, 39, 57, 247, 741
513 : 1, 3, 9, 19, 27, 57, 171, 513
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,278,809,741,513, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
278:2x 139
809:809
741:3x 13x 19
513:3x 3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 19 = 114
Therefore, the value for common factors is 114.
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 = 78653258208720/(1x114)
LCM = 78653258208720/114
LCM = 689940861480
Thus, we can understand that the LCM of 920,278,809,741,513 is 689940861480.
