Given numbers are 543,779,779,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 543,779,779,861 is 2960979.
Find LCM of 543,779,779,861 with Prime Factorization
| 3 | 543, 779, 779, 861 |
| 19 | 181, 779, 779, 287 |
| 41 | 181, 41, 41, 287 |
| 181, 1, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 41 x 181 x 1 x 1 x 7 = 2960979
Therefore, the lowest common multiple of 543,779,779,861 is 2960979.
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.
543 x 779 x 779 x 861 = 283712124843
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.
543 : 1, 3, 181, 543
779 : 1, 19, 41, 779
779 : 1, 19, 41, 779
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,779,779,861, is 1.
Now, the common factors can be found like this.
543:3x 181
779:19x 41
779:19x 41
861:3x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19x 41x 41 = 95817
Therefore, the value for common factors is 95817.
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 = 283712124843/(1x95817)
LCM = 283712124843/95817
LCM = 2960979
Thus, we can understand that the LCM of 543,779,779,861 is 2960979.
