Given numbers are 171,869,741,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 171,869,741,921 is 593058609.
Find LCM of 171,869,741,921 with Prime Factorization
| 3 | 171, 869, 741, 921 |
| 19 | 57, 869, 247, 307 |
| 3, 869, 13, 307 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 3 x 869 x 13 x 307 = 593058609
Therefore, the lowest common multiple of 171,869,741,921 is 593058609.
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.
171 x 869 x 741 x 921 = 101413022139
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.
171 : 1, 3, 9, 19, 57, 171
869 : 1, 11, 79, 869
741 : 1, 3, 13, 19, 39, 57, 247, 741
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,869,741,921, is 1.
Now, the common factors can be found like this.
171:3x 3x 19
869:11x 79
741:3x 13x 19
921:3x 307
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 19 = 171
Therefore, the value for common factors is 171.
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 = 101413022139/(1x171)
LCM = 101413022139/171
LCM = 593058609
Thus, we can understand that the LCM of 171,869,741,921 is 593058609.
