Given numbers are 861,886,984,118
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,886,984,118 is 180031656.
Find LCM of 861,886,984,118 with Prime Factorization
| 2 | 861, 886, 984, 118 |
| 3 | 861, 443, 492, 59 |
| 41 | 287, 443, 164, 59 |
| 7, 443, 4, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 41 x 7 x 443 x 4 x 59 = 180031656
Therefore, the lowest common multiple of 861,886,984,118 is 180031656.
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.
861 x 886 x 984 x 118 = 88575574752
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
886 : 1, 2, 443, 886
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
118 : 1, 2, 59, 118
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,886,984,118, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
886:2x 443
984:2x 2x 2x 3x 41
118:2x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 41 = 492
Therefore, the value for common factors is 492.
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 = 88575574752/(1x492)
LCM = 88575574752/492
LCM = 180031656
Thus, we can understand that the LCM of 861,886,984,118 is 180031656.
