Given numbers are 543,665,779,969
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 543,665,779,969 is 251683215.
Find LCM of 543,665,779,969 with Prime Factorization
| 3 | 543, 665, 779, 969 |
| 19 | 181, 665, 779, 323 |
| 181, 35, 41, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 181 x 35 x 41 x 17 = 251683215
Therefore, the lowest common multiple of 543,665,779,969 is 251683215.
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 665 x 779 x 969 = 272572921845
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
665 : 1, 5, 7, 19, 35, 95, 133, 665
779 : 1, 19, 41, 779
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,665,779,969, is 1.
Now, the common factors can be found like this.
543:3x 181
665:5x 7x 19
779:19x 41
969:3x 17x 19
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 19 = 1083
Therefore, the value for common factors is 1083.
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 = 272572921845/(1x1083)
LCM = 272572921845/1083
LCM = 251683215
Thus, we can understand that the LCM of 543,665,779,969 is 251683215.
