Find LCM of 262,378,217,783,621 with Prime Factorization
| 2 | 262, 378, 217, 783, 621 |
| 3 | 131, 189, 217, 783, 621 |
| 3 | 131, 63, 217, 261, 207 |
| 3 | 131, 21, 217, 87, 69 |
| 7 | 131, 7, 217, 29, 23 |
| 131, 1, 31, 29, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 131 x 1 x 31 x 29 x 23 = 1023883686
Therefore, the lowest common multiple of 262,378,217,783,621 is 1023883686.
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.
262 x 378 x 217 x 783 x 621 = 10449756899316
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.
262 : 1, 2, 131, 262
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
217 : 1, 7, 31, 217
783 : 1, 3, 9, 27, 29, 87, 261, 783
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 262,378,217,783,621, is 1.
Now, the common factors can be found like this.
262:2x 131
378:2x 3x 3x 3x 7
217:7x 31
783:3x 3x 3x 29
621:3x 3x 3x 23
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 3x 3x 3x 3x 7 = 10206
Therefore, the value for common factors is 10206.
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 = 10449756899316/(1x10206)
LCM = 10449756899316/10206
LCM = 1023883686
Thus, we can understand that the LCM of 262,378,217,783,621 is 1023883686.
