Given numbers are 385,401,724,752,845
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 385,401,724,752,845 is 3551307039280.
Find LCM of 385,401,724,752,845 with Prime Factorization
| 2 | 385, 401, 724, 752, 845 |
| 2 | 385, 401, 362, 376, 845 |
| 5 | 385, 401, 181, 188, 845 |
| 77, 401, 181, 188, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 77 x 401 x 181 x 188 x 169 = 3551307039280
Therefore, the lowest common multiple of 385,401,724,752,845 is 3551307039280.
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.
385 x 401 x 724 x 752 x 845 = 71026140785600
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.
385 : 1, 5, 7, 11, 35, 55, 77, 385
401 : 1, 401
724 : 1, 2, 4, 181, 362, 724
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,401,724,752,845, is 1.
Now, the common factors can be found like this.
385:5x 7x 11
401:401
724:2x 2x 181
752:2x 2x 2x 2x 47
845:5x 13x 13
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 5 = 20
Therefore, the value for common factors is 20.
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 = 71026140785600/(1x20)
LCM = 71026140785600/20
LCM = 3551307039280
Thus, we can understand that the LCM of 385,401,724,752,845 is 3551307039280.
