Find LCM of 684,841,261,434,620 with Prime Factorization
| 2 | 684, 841, 261, 434, 620 |
| 2 | 342, 841, 261, 217, 310 |
| 3 | 171, 841, 261, 217, 155 |
| 3 | 57, 841, 87, 217, 155 |
| 29 | 19, 841, 29, 217, 155 |
| 31 | 19, 1, 29, 217, 155 |
| 19, 1, 29, 7, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 29 x 31 x 19 x 1 x 29 x 7 x 5 = 624139740
Therefore, the lowest common multiple of 684,841,261,434,620 is 624139740.
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.
684 x 841 x 261 x 434 x 620 = 40399317090720
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
841 : 1, 29, 841
261 : 1, 3, 9, 29, 87, 261
434 : 1, 2, 7, 14, 31, 62, 217, 434
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,841,261,434,620, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
841:29x 29
261:3x 3x 29
434:2x 7x 31
620:2x 2x 5x 31
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 2x 3x 3x 29x 31 = 64728
Therefore, the value for common factors is 64728.
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 = 40399317090720/(1x64728)
LCM = 40399317090720/64728
LCM = 624139740
Thus, we can understand that the LCM of 684,841,261,434,620 is 624139740.
