Given numbers are 914,945,686,914
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 914,945,686,914 is 42322770.
Find LCM of 914,945,686,914 with Prime Factorization
| 2 | 914, 945, 686, 914 |
| 7 | 457, 945, 343, 457 |
| 457 | 457, 135, 49, 457 |
| 1, 135, 49, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 457 x 1 x 135 x 49 x 1 = 42322770
Therefore, the lowest common multiple of 914,945,686,914 is 42322770.
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.
914 x 945 x 686 x 914 = 541562164920
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.
914 : 1, 2, 457, 914
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
686 : 1, 2, 7, 14, 49, 98, 343, 686
914 : 1, 2, 457, 914
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 914,945,686,914, is 1.
Now, the common factors can be found like this.
914:2x 457
945:3x 3x 3x 5x 7
686:2x 7x 7x 7
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 7x 457 = 12796
Therefore, the value for common factors is 12796.
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 = 541562164920/(1x12796)
LCM = 541562164920/12796
LCM = 42322770
Thus, we can understand that the LCM of 914,945,686,914 is 42322770.
