Find LCM of 247,475,216,390,321 with Prime Factorization
| 2 | 247, 475, 216, 390, 321 |
| 3 | 247, 475, 108, 195, 321 |
| 5 | 247, 475, 36, 65, 107 |
| 13 | 247, 95, 36, 13, 107 |
| 19 | 19, 95, 36, 1, 107 |
| 1, 5, 36, 1, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 19 x 1 x 5 x 36 x 1 x 107 = 142716600
Therefore, the lowest common multiple of 247,475,216,390,321 is 142716600.
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 475 x 216 x 390 x 321 = 3172590018000
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
475 : 1, 5, 19, 25, 95, 475
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,475,216,390,321, is 1.
Now, the common factors can be found like this.
247:13x 19
475:5x 5x 19
216:2x 2x 2x 3x 3x 3
390:2x 3x 5x 13
321:3x 107
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 5x 13x 19 = 22230
Therefore, the value for common factors is 22230.
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 = 3172590018000/(1x22230)
LCM = 3172590018000/22230
LCM = 142716600
Thus, we can understand that the LCM of 247,475,216,390,321 is 142716600.
