Given numbers are 871,280,266,798
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 871,280,266,798 is 13901160.
Find LCM of 871,280,266,798 with Prime Factorization
2 | 871, 280, 266, 798 |
7 | 871, 140, 133, 399 |
19 | 871, 20, 19, 57 |
871, 20, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 871 x 20 x 1 x 3 = 13901160
Therefore, the lowest common multiple of 871,280,266,798 is 13901160.
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.
871 x 280 x 266 x 798 = 51767919840
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.
871 : 1, 13, 67, 871
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
266 : 1, 2, 7, 14, 19, 38, 133, 266
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,280,266,798, is 1.
Now, the common factors can be found like this.
871:13x 67
280:2x 2x 2x 5x 7
266:2x 7x 19
798:2x 3x 7x 19
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 7x 7x 19 = 3724
Therefore, the value for common factors is 3724.
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 = 51767919840/(1x3724)
LCM = 51767919840/3724
LCM = 13901160
Thus, we can understand that the LCM of 871,280,266,798 is 13901160.
