The LCM of 891,841,812,423,180 is 4930597980.
Find LCM of 891,841,812,423,180 with Prime Factorization
| 2 | 891, 841, 812, 423, 180 |
| 2 | 891, 841, 406, 423, 90 |
| 3 | 891, 841, 203, 423, 45 |
| 3 | 297, 841, 203, 141, 15 |
| 29 | 99, 841, 203, 47, 5 |
| 99, 29, 7, 47, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 29 x 99 x 29 x 7 x 47 x 5 = 4930597980
Therefore, the lowest common multiple of 891,841,812,423,180 is 4930597980.
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.
891 x 841 x 812 x 423 x 180 = 46327898620080
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
841 : 1, 29, 841
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
423 : 1, 3, 9, 47, 141, 423
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,841,812,423,180, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
841:29x 29
812:2x 2x 7x 29
423:3x 3x 47
180:2x 2x 3x 3x 5
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 3x 3x 29 = 9396
Therefore, the value for common factors is 9396.
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 = 46327898620080/(1x9396)
LCM = 46327898620080/9396
LCM = 4930597980
Thus, we can understand that the LCM of 891,841,812,423,180 is 4930597980.
