Given numbers are 558,561,791,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 558,561,791,961 is 2558668266.
Find LCM of 558,561,791,961 with Prime Factorization
| 3 | 558, 561, 791, 961 |
| 31 | 186, 187, 791, 961 |
| 6, 187, 791, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 31 x 6 x 187 x 791 x 31 = 2558668266
Therefore, the lowest common multiple of 558,561,791,961 is 2558668266.
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.
558 x 561 x 791 x 961 = 237956148738
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.
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
561 : 1, 3, 11, 17, 33, 51, 187, 561
791 : 1, 7, 113, 791
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,561,791,961, is 1.
Now, the common factors can be found like this.
558:2x 3x 3x 31
561:3x 11x 17
791:7x 113
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 31 = 93
Therefore, the value for common factors is 93.
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 = 237956148738/(1x93)
LCM = 237956148738/93
LCM = 2558668266
Thus, we can understand that the LCM of 558,561,791,961 is 2558668266.
