Given numbers are 417,853,555,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 417,853,555,821 is 54025646385.
Find LCM of 417,853,555,821 with Prime Factorization
| 3 | 417, 853, 555, 821 |
| 139, 853, 185, 821 |
Multiply the prime numbers at the bottom and the left side.
3 x 139 x 853 x 185 x 821 = 54025646385
Therefore, the lowest common multiple of 417,853,555,821 is 54025646385.
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.
417 x 853 x 555 x 821 = 162076939155
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.
417 : 1, 3, 139, 417
853 : 1, 853
555 : 1, 3, 5, 15, 37, 111, 185, 555
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,853,555,821, is 1.
Now, the common factors can be found like this.
417:3x 139
853:853
555:3x 5x 37
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 162076939155/(1x3)
LCM = 162076939155/3
LCM = 54025646385
Thus, we can understand that the LCM of 417,853,555,821 is 54025646385.
