Given numbers are 823,438,823,747,900
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 823,438,823,747,900 is 4487901300.
Find LCM of 823,438,823,747,900 with Prime Factorization
| 2 | 823, 438, 823, 747, 900 |
| 3 | 823, 219, 823, 747, 450 |
| 3 | 823, 73, 823, 249, 150 |
| 823 | 823, 73, 823, 83, 50 |
| 1, 73, 1, 83, 50 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 823 x 1 x 73 x 1 x 83 x 50 = 4487901300
Therefore, the lowest common multiple of 823,438,823,747,900 is 4487901300.
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 438 x 823 x 747 x 900 = 199451309574600
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
438 : 1, 2, 3, 6, 73, 146, 219, 438
823 : 1, 823
747 : 1, 3, 9, 83, 249, 747
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,438,823,747,900, is 1.
Now, the common factors can be found like this.
823:823
438:2x 3x 73
823:823
747:3x 3x 83
900:2x 2x 3x 3x 5x 5
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 3x 3x 823 = 44442
Therefore, the value for common factors is 44442.
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 = 199451309574600/(1x44442)
LCM = 199451309574600/44442
LCM = 4487901300
Thus, we can understand that the LCM of 823,438,823,747,900 is 4487901300.
