Given numbers are 215,775,921,900,997
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 215,775,921,900,997 is 367202976300.
Find LCM of 215,775,921,900,997 with Prime Factorization
| 3 | 215, 775, 921, 900, 997 |
| 5 | 215, 775, 307, 300, 997 |
| 5 | 43, 155, 307, 60, 997 |
| 43, 31, 307, 12, 997 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 5 x 43 x 31 x 307 x 12 x 997 = 367202976300
Therefore, the lowest common multiple of 215,775,921,900,997 is 367202976300.
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.
215 x 775 x 921 x 900 x 997 = 137701116112500
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.
215 : 1, 5, 43, 215
775 : 1, 5, 25, 31, 155, 775
921 : 1, 3, 307, 921
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
997 : 1, 997
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 215,775,921,900,997, is 1.
Now, the common factors can be found like this.
215:5x 43
775:5x 5x 31
921:3x 307
900:2x 2x 3x 3x 5x 5
997:997
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 5 = 375
Therefore, the value for common factors is 375.
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 = 137701116112500/(1x375)
LCM = 137701116112500/375
LCM = 367202976300
Thus, we can understand that the LCM of 215,775,921,900,997 is 367202976300.
