Given numbers are 686,529,770,540,914
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,529,770,540,914 is 492552397260.
Find LCM of 686,529,770,540,914 with Prime Factorization
| 2 | 686, 529, 770, 540, 914 |
| 5 | 343, 529, 385, 270, 457 |
| 7 | 343, 529, 77, 54, 457 |
| 49, 529, 11, 54, 457 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 49 x 529 x 11 x 54 x 457 = 492552397260
Therefore, the lowest common multiple of 686,529,770,540,914 is 492552397260.
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 529 x 770 x 540 x 914 = 137914671232800
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
529 : 1, 23, 529
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
914 : 1, 2, 457, 914
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,529,770,540,914, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
529:23x 23
770:2x 5x 7x 11
540:2x 2x 3x 3x 3x 5
914:2x 457
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 137914671232800/(1x280)
LCM = 137914671232800/280
LCM = 492552397260
Thus, we can understand that the LCM of 686,529,770,540,914 is 492552397260.
