Given numbers are 823,738,450,947,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 823,738,450,947,686 is 4932195751350.
Find LCM of 823,738,450,947,686 with Prime Factorization
| 2 | 823, 738, 450, 947, 686 |
| 3 | 823, 369, 225, 947, 343 |
| 3 | 823, 123, 75, 947, 343 |
| 823, 41, 25, 947, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 823 x 41 x 25 x 947 x 343 = 4932195751350
Therefore, the lowest common multiple of 823,738,450,947,686 is 4932195751350.
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.
823 x 738 x 450 x 947 x 686 = 177559047048600
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.
823 : 1, 823
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
947 : 1, 947
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,738,450,947,686, is 1.
Now, the common factors can be found like this.
823:823
738:2x 3x 3x 41
450:2x 3x 3x 5x 5
947:947
686:2x 7x 7x 7
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 3 = 36
Therefore, the value for common factors is 36.
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 = 177559047048600/(1x36)
LCM = 177559047048600/36
LCM = 4932195751350
Thus, we can understand that the LCM of 823,738,450,947,686 is 4932195751350.
