Given numbers are 171,861,107,747,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 171,861,107,747,909 is 44021136537.
Find LCM of 171,861,107,747,909 with Prime Factorization
3 | 171, 861, 107, 747, 909 |
3 | 57, 287, 107, 249, 303 |
19, 287, 107, 83, 101 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 19 x 287 x 107 x 83 x 101 = 44021136537
Therefore, the lowest common multiple of 171,861,107,747,909 is 44021136537.
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 861 x 107 x 747 x 909 = 10697136178491
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
861 : 1, 3, 7, 21, 41, 123, 287, 861
107 : 1, 107
747 : 1, 3, 9, 83, 249, 747
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,861,107,747,909, is 1.
Now, the common factors can be found like this.
171:3x 3x 19
861:3x 7x 41
107:107
747:3x 3x 83
909:3x 3x 101
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 3x 3x 3 = 243
Therefore, the value for common factors is 243.
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 = 10697136178491/(1x243)
LCM = 10697136178491/243
LCM = 44021136537
Thus, we can understand that the LCM of 171,861,107,747,909 is 44021136537.
