Given numbers are 486,408,962,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 486,408,962,780 is 79480440.
Find LCM of 486,408,962,780 with Prime Factorization
| 2 | 486, 408, 962, 780 |
| 2 | 243, 204, 481, 390 |
| 3 | 243, 102, 481, 195 |
| 13 | 81, 34, 481, 65 |
| 81, 34, 37, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 81 x 34 x 37 x 5 = 79480440
Therefore, the lowest common multiple of 486,408,962,780 is 79480440.
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.
486 x 408 x 962 x 780 = 148787383680
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.
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
962 : 1, 2, 13, 26, 37, 74, 481, 962
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 486,408,962,780, is 2.
Now, the common factors can be found like this.
486:2x 3x 3x 3x 3x 3
408:2x 2x 2x 3x 17
962:2x 13x 37
780:2x 2x 3x 5x 13
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 3x 13 = 936
Therefore, the value for common factors is 936.
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 = 148787383680/(2x936)
LCM = 148787383680/1872
LCM = 79480440
Thus, we can understand that the LCM of 486,408,962,780 is 79480440.
