Given numbers are 161,863,628,207,863
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,863,628,207,863 is 785305836.
Find LCM of 161,863,628,207,863 with Prime Factorization
| 23 | 161, 863, 628, 207, 863 |
| 863 | 7, 863, 628, 9, 863 |
| 7, 1, 628, 9, 1 |
Multiply the prime numbers at the bottom and the left side.
23 x 863 x 7 x 1 x 628 x 9 x 1 = 785305836
Therefore, the lowest common multiple of 161,863,628,207,863 is 785305836.
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.
161 x 863 x 628 x 207 x 863 = 15587535538764
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.
161 : 1, 7, 23, 161
863 : 1, 863
628 : 1, 2, 4, 157, 314, 628
207 : 1, 3, 9, 23, 69, 207
863 : 1, 863
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,863,628,207,863, is 1.
Now, the common factors can be found like this.
161:7x 23
863:863
628:2x 2x 157
207:3x 3x 23
863:863
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 863 = 19849
Therefore, the value for common factors is 19849.
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 = 15587535538764/(1x19849)
LCM = 15587535538764/19849
LCM = 785305836
Thus, we can understand that the LCM of 161,863,628,207,863 is 785305836.
