Given numbers are 821,917,900,505,932
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,917,900,505,932 is 15945285402900.
Find LCM of 821,917,900,505,932 with Prime Factorization
| 2 | 821, 917, 900, 505, 932 |
| 2 | 821, 917, 450, 505, 466 |
| 5 | 821, 917, 225, 505, 233 |
| 821, 917, 45, 101, 233 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 821 x 917 x 45 x 101 x 233 = 15945285402900
Therefore, the lowest common multiple of 821,917,900,505,932 is 15945285402900.
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.
821 x 917 x 900 x 505 x 932 = 318905708058000
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.
821 : 1, 821
917 : 1, 7, 131, 917
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
505 : 1, 5, 101, 505
932 : 1, 2, 4, 233, 466, 932
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,917,900,505,932, is 1.
Now, the common factors can be found like this.
821:821
917:7x 131
900:2x 2x 3x 3x 5x 5
505:5x 101
932:2x 2x 233
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 5 = 20
Therefore, the value for common factors is 20.
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 = 318905708058000/(1x20)
LCM = 318905708058000/20
LCM = 15945285402900
Thus, we can understand that the LCM of 821,917,900,505,932 is 15945285402900.
