Find LCM of 721,812,968,873,899 with Prime Factorization
| 2 | 721, 812, 968, 873, 899 |
| 2 | 721, 406, 484, 873, 899 |
| 7 | 721, 203, 242, 873, 899 |
| 29 | 103, 29, 242, 873, 899 |
| 103, 1, 242, 873, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 29 x 103 x 1 x 242 x 873 x 31 = 547752738456
Therefore, the lowest common multiple of 721,812,968,873,899 is 547752738456.
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.
721 x 812 x 968 x 873 x 899 = 444775223626272
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.
721 : 1, 7, 103, 721
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
873 : 1, 3, 9, 97, 291, 873
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,812,968,873,899, is 1.
Now, the common factors can be found like this.
721:7x 103
812:2x 2x 7x 29
968:2x 2x 2x 11x 11
873:3x 3x 97
899:29x 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 7x 29 = 812
Therefore, the value for common factors is 812.
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 = 444775223626272/(1x812)
LCM = 444775223626272/812
LCM = 547752738456
Thus, we can understand that the LCM of 721,812,968,873,899 is 547752738456.
