Given numbers are 830,781,993,162,777
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 830,781,993,162,777 is 4501340883270.
Find LCM of 830,781,993,162,777 with Prime Factorization
| 2 | 830, 781, 993, 162, 777 |
| 3 | 415, 781, 993, 81, 777 |
| 415, 781, 331, 27, 259 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 415 x 781 x 331 x 27 x 259 = 4501340883270
Therefore, the lowest common multiple of 830,781,993,162,777 is 4501340883270.
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.
830 x 781 x 993 x 162 x 777 = 81024135898860
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.
830 : 1, 2, 5, 10, 83, 166, 415, 830
781 : 1, 11, 71, 781
993 : 1, 3, 331, 993
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
777 : 1, 3, 7, 21, 37, 111, 259, 777
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,781,993,162,777, is 1.
Now, the common factors can be found like this.
830:2x 5x 83
781:11x 71
993:3x 331
162:2x 3x 3x 3x 3
777:3x 7x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 81024135898860/(1x18)
LCM = 81024135898860/18
LCM = 4501340883270
Thus, we can understand that the LCM of 830,781,993,162,777 is 4501340883270.
