Given numbers are 561,543,854,959
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,543,854,959 is 11880093918.
Find LCM of 561,543,854,959 with Prime Factorization
| 3 | 561, 543, 854, 959 |
| 7 | 187, 181, 854, 959 |
| 187, 181, 122, 137 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 187 x 181 x 122 x 137 = 11880093918
Therefore, the lowest common multiple of 561,543,854,959 is 11880093918.
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.
561 x 543 x 854 x 959 = 249481972278
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
543 : 1, 3, 181, 543
854 : 1, 2, 7, 14, 61, 122, 427, 854
959 : 1, 7, 137, 959
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,543,854,959, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
543:3x 181
854:2x 7x 61
959:7x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 249481972278/(1x21)
LCM = 249481972278/21
LCM = 11880093918
Thus, we can understand that the LCM of 561,543,854,959 is 11880093918.
