Given numbers are 421,813,966,149
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,813,966,149 is 16421573994.
Find LCM of 421,813,966,149 with Prime Factorization
3 | 421, 813, 966, 149 |
421, 271, 322, 149 |
Multiply the prime numbers at the bottom and the left side.
3 x 421 x 271 x 322 x 149 = 16421573994
Therefore, the lowest common multiple of 421,813,966,149 is 16421573994.
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.
421 x 813 x 966 x 149 = 49264721982
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.
421 : 1, 421
813 : 1, 3, 271, 813
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
149 : 1, 149
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,813,966,149, is 1.
Now, the common factors can be found like this.
421:421
813:3x 271
966:2x 3x 7x 23
149:149
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 = 49264721982/(1x3)
LCM = 49264721982/3
LCM = 16421573994
Thus, we can understand that the LCM of 421,813,966,149 is 16421573994.
