Given numbers are 350,686,871,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 350,686,871,561 is 8380021650.
Find LCM of 350,686,871,561 with Prime Factorization
| 2 | 350, 686, 871, 561 |
| 7 | 175, 343, 871, 561 |
| 25, 49, 871, 561 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 25 x 49 x 871 x 561 = 8380021650
Therefore, the lowest common multiple of 350,686,871,561 is 8380021650.
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.
350 x 686 x 871 x 561 = 117320303100
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.
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
686 : 1, 2, 7, 14, 49, 98, 343, 686
871 : 1, 13, 67, 871
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 350,686,871,561, is 1.
Now, the common factors can be found like this.
350:2x 5x 5x 7
686:2x 7x 7x 7
871:13x 67
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 117320303100/(1x14)
LCM = 117320303100/14
LCM = 8380021650
Thus, we can understand that the LCM of 350,686,871,561 is 8380021650.
