Given numbers are 221,897,393,131
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,897,393,131 is 1997619.
Find LCM of 221,897,393,131 with Prime Factorization
| 3 | 221, 897, 393, 131 |
| 13 | 221, 299, 131, 131 |
| 131 | 17, 23, 131, 131 |
| 17, 23, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 131 x 17 x 23 x 1 x 1 = 1997619
Therefore, the lowest common multiple of 221,897,393,131 is 1997619.
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.
221 x 897 x 393 x 131 = 10205835471
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.
221 : 1, 13, 17, 221
897 : 1, 3, 13, 23, 39, 69, 299, 897
393 : 1, 3, 131, 393
131 : 1, 131
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,897,393,131, is 1.
Now, the common factors can be found like this.
221:13x 17
897:3x 13x 23
393:3x 131
131:131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 131 = 5109
Therefore, the value for common factors is 5109.
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 = 10205835471/(1x5109)
LCM = 10205835471/5109
LCM = 1997619
Thus, we can understand that the LCM of 221,897,393,131 is 1997619.
