Given numbers are 411,722,821,411
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 411,722,821,411 is 243625182.
Find LCM of 411,722,821,411 with Prime Factorization
| 3 | 411, 722, 821, 411 |
| 137 | 137, 722, 821, 137 |
| 1, 722, 821, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 137 x 1 x 722 x 821 x 1 = 243625182
Therefore, the lowest common multiple of 411,722,821,411 is 243625182.
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.
411 x 722 x 821 x 411 = 100129949802
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.
411 : 1, 3, 137, 411
722 : 1, 2, 19, 38, 361, 722
821 : 1, 821
411 : 1, 3, 137, 411
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 411,722,821,411, is 1.
Now, the common factors can be found like this.
411:3x 137
722:2x 19x 19
821:821
411:3x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 137 = 411
Therefore, the value for common factors is 411.
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 = 100129949802/(1x411)
LCM = 100129949802/411
LCM = 243625182
Thus, we can understand that the LCM of 411,722,821,411 is 243625182.
