Given numbers are 127,830,617,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 127,830,617,855 is 11121492870.
Find LCM of 127,830,617,855 with Prime Factorization
| 5 | 127, 830, 617, 855 |
| 127, 166, 617, 171 |
Multiply the prime numbers at the bottom and the left side.
5 x 127 x 166 x 617 x 171 = 11121492870
Therefore, the lowest common multiple of 127,830,617,855 is 11121492870.
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.
127 x 830 x 617 x 855 = 55607464350
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.
127 : 1, 127
830 : 1, 2, 5, 10, 83, 166, 415, 830
617 : 1, 617
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 127,830,617,855, is 1.
Now, the common factors can be found like this.
127:127
830:2x 5x 83
617:617
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 55607464350/(1x5)
LCM = 55607464350/5
LCM = 11121492870
Thus, we can understand that the LCM of 127,830,617,855 is 11121492870.
