Given numbers are 266,871,680,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 266,871,680,442 is 78773240.
Find LCM of 266,871,680,442 with Prime Factorization
| 2 | 266, 871, 680, 442 |
| 13 | 133, 871, 340, 221 |
| 17 | 133, 67, 340, 17 |
| 133, 67, 20, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 133 x 67 x 20 x 1 = 78773240
Therefore, the lowest common multiple of 266,871,680,442 is 78773240.
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.
266 x 871 x 680 x 442 = 69635544160
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.
266 : 1, 2, 7, 14, 19, 38, 133, 266
871 : 1, 13, 67, 871
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 266,871,680,442, is 1.
Now, the common factors can be found like this.
266:2x 7x 19
871:13x 67
680:2x 2x 2x 5x 17
442:2x 13x 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 2x 13x 17 = 884
Therefore, the value for common factors is 884.
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 = 69635544160/(1x884)
LCM = 69635544160/884
LCM = 78773240
Thus, we can understand that the LCM of 266,871,680,442 is 78773240.
