Given numbers are 681,881,468,189
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,881,468,189 is 1965472236.
Find LCM of 681,881,468,189 with Prime Factorization
3 | 681, 881, 468, 189 |
3 | 227, 881, 156, 63 |
227, 881, 52, 21 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 227 x 881 x 52 x 21 = 1965472236
Therefore, the lowest common multiple of 681,881,468,189 is 1965472236.
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.
681 x 881 x 468 x 189 = 53067750372
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.
681 : 1, 3, 227, 681
881 : 1, 881
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,881,468,189, is 1.
Now, the common factors can be found like this.
681:3x 227
881:881
468:2x 2x 3x 3x 13
189:3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3 = 27
Therefore, the value for common factors is 27.
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 = 53067750372/(1x27)
LCM = 53067750372/27
LCM = 1965472236
Thus, we can understand that the LCM of 681,881,468,189 is 1965472236.
