Given numbers are 811,242,360,228,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,242,360,228,721 is 483946764840.
Find LCM of 811,242,360,228,721 with Prime Factorization
| 2 | 811, 242, 360, 228, 721 |
| 2 | 811, 121, 180, 114, 721 |
| 3 | 811, 121, 90, 57, 721 |
| 811, 121, 30, 19, 721 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 811 x 121 x 30 x 19 x 721 = 483946764840
Therefore, the lowest common multiple of 811,242,360,228,721 is 483946764840.
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.
811 x 242 x 360 x 228 x 721 = 11614722356160
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.
811 : 1, 811
242 : 1, 2, 11, 22, 121, 242
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,242,360,228,721, is 1.
Now, the common factors can be found like this.
811:811
242:2x 11x 11
360:2x 2x 2x 3x 3x 5
228:2x 2x 3x 19
721:7x 103
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 3 = 24
Therefore, the value for common factors is 24.
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 = 11614722356160/(1x24)
LCM = 11614722356160/24
LCM = 483946764840
Thus, we can understand that the LCM of 811,242,360,228,721 is 483946764840.
