Find LCM of 315,997,306,160,238 with Prime Factorization
| 2 | 315, 997, 306, 160, 238 |
| 3 | 315, 997, 153, 80, 119 |
| 3 | 105, 997, 51, 80, 119 |
| 5 | 35, 997, 17, 80, 119 |
| 7 | 7, 997, 17, 16, 119 |
| 17 | 1, 997, 17, 16, 17 |
| 1, 997, 1, 16, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 17 x 1 x 997 x 1 x 16 x 1 = 170845920
Therefore, the lowest common multiple of 315,997,306,160,238 is 170845920.
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.
315 x 997 x 306 x 160 x 238 = 3659519606400
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
997 : 1, 997
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
238 : 1, 2, 7, 14, 17, 34, 119, 238
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,997,306,160,238, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
997:997
306:2x 3x 3x 17
160:2x 2x 2x 2x 2x 5
238:2x 7x 17
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 3x 5x 7x 17 = 21420
Therefore, the value for common factors is 21420.
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 = 3659519606400/(1x21420)
LCM = 3659519606400/21420
LCM = 170845920
Thus, we can understand that the LCM of 315,997,306,160,238 is 170845920.
