The LCM of 812,494,684,875 is 225634500.
Find LCM of 812,494,684,875 with Prime Factorization
| 2 | 812, 494, 684, 875 |
| 2 | 406, 247, 342, 875 |
| 7 | 203, 247, 171, 875 |
| 19 | 29, 247, 171, 125 |
| 29, 13, 9, 125 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 19 x 29 x 13 x 9 x 125 = 225634500
Therefore, the lowest common multiple of 812,494,684,875 is 225634500.
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.
812 x 494 x 684 x 875 = 240075108000
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
494 : 1, 2, 13, 19, 26, 38, 247, 494
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
875 : 1, 5, 7, 25, 35, 125, 175, 875
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,494,684,875, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
494:2x 13x 19
684:2x 2x 3x 3x 19
875:5x 5x 5x 7
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 7x 19 = 1064
Therefore, the value for common factors is 1064.
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 = 240075108000/(1x1064)
LCM = 240075108000/1064
LCM = 225634500
Thus, we can understand that the LCM of 812,494,684,875 is 225634500.
