Given numbers are 401,897,387,862,187
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,897,387,862,187 is 7479548770122.
Find LCM of 401,897,387,862,187 with Prime Factorization
| 3 | 401, 897, 387, 862, 187 |
| 401, 299, 129, 862, 187 |
Multiply the prime numbers at the bottom and the left side.
3 x 401 x 299 x 129 x 862 x 187 = 7479548770122
Therefore, the lowest common multiple of 401,897,387,862,187 is 7479548770122.
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.
401 x 897 x 387 x 862 x 187 = 22438646310366
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.
401 : 1, 401
897 : 1, 3, 13, 23, 39, 69, 299, 897
387 : 1, 3, 9, 43, 129, 387
862 : 1, 2, 431, 862
187 : 1, 11, 17, 187
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,897,387,862,187, is 1.
Now, the common factors can be found like this.
401:401
897:3x 13x 23
387:3x 3x 43
862:2x 431
187:11x 17
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 = 22438646310366/(1x3)
LCM = 22438646310366/3
LCM = 7479548770122
Thus, we can understand that the LCM of 401,897,387,862,187 is 7479548770122.
