Given numbers are 686,599,428,861,608
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,599,428,861,608 is 1644043902816.
Find LCM of 686,599,428,861,608 with Prime Factorization
| 2 | 686, 599, 428, 861, 608 |
| 2 | 343, 599, 214, 861, 304 |
| 7 | 343, 599, 107, 861, 152 |
| 49, 599, 107, 123, 152 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 49 x 599 x 107 x 123 x 152 = 1644043902816
Therefore, the lowest common multiple of 686,599,428,861,608 is 1644043902816.
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.
686 x 599 x 428 x 861 x 608 = 92066458557696
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
599 : 1, 599
428 : 1, 2, 4, 107, 214, 428
861 : 1, 3, 7, 21, 41, 123, 287, 861
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,599,428,861,608, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
599:599
428:2x 2x 107
861:3x 7x 41
608:2x 2x 2x 2x 2x 19
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 2x 7 = 56
Therefore, the value for common factors is 56.
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 = 92066458557696/(1x56)
LCM = 92066458557696/56
LCM = 1644043902816
Thus, we can understand that the LCM of 686,599,428,861,608 is 1644043902816.
