Find LCM of 247,331,480,975,997 with Prime Factorization
| 3 | 247, 331, 480, 975, 997 |
| 5 | 247, 331, 160, 325, 997 |
| 13 | 247, 331, 32, 65, 997 |
| 19, 331, 32, 5, 997 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 19 x 331 x 32 x 5 x 997 = 195628149600
Therefore, the lowest common multiple of 247,331,480,975,997 is 195628149600.
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.
247 x 331 x 480 x 975 x 997 = 38147489172000
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.
247 : 1, 13, 19, 247
331 : 1, 331
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
997 : 1, 997
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,331,480,975,997, is 1.
Now, the common factors can be found like this.
247:13x 19
331:331
480:2x 2x 2x 2x 2x 3x 5
975:3x 5x 5x 13
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 13 = 195
Therefore, the value for common factors is 195.
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 = 38147489172000/(1x195)
LCM = 38147489172000/195
LCM = 195628149600
Thus, we can understand that the LCM of 247,331,480,975,997 is 195628149600.
