Given numbers are 821,300,401,818
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 821,300,401,818 is 40395416700.
Find LCM of 821,300,401,818 with Prime Factorization
| 2 | 821, 300, 401, 818 |
| 821, 150, 401, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 821 x 150 x 401 x 409 = 40395416700
Therefore, the lowest common multiple of 821,300,401,818 is 40395416700.
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.
821 x 300 x 401 x 818 = 80790833400
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.
821 : 1, 821
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
401 : 1, 401
818 : 1, 2, 409, 818
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,300,401,818, is 1.
Now, the common factors can be found like this.
821:821
300:2x 2x 3x 5x 5
401:401
818:2x 409
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 80790833400/(1x2)
LCM = 80790833400/2
LCM = 40395416700
Thus, we can understand that the LCM of 821,300,401,818 is 40395416700.
