Given numbers are 871,458,868,665,288
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 871,458,868,665,288 is 1184212018080.
Find LCM of 871,458,868,665,288 with Prime Factorization
2 | 871, 458, 868, 665, 288 |
2 | 871, 229, 434, 665, 144 |
7 | 871, 229, 217, 665, 72 |
871, 229, 31, 95, 72 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 871 x 229 x 31 x 95 x 72 = 1184212018080
Therefore, the lowest common multiple of 871,458,868,665,288 is 1184212018080.
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 458 x 868 x 665 x 288 = 66315873012480
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
458 : 1, 2, 229, 458
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
665 : 1, 5, 7, 19, 35, 95, 133, 665
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,458,868,665,288, is 1.
Now, the common factors can be found like this.
871:13x 67
458:2x 229
868:2x 2x 7x 31
665:5x 7x 19
288:2x 2x 2x 2x 2x 3x 3
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 2x 7 = 56
Therefore, the value for common factors is 56.
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 = 66315873012480/(1x56)
LCM = 66315873012480/56
LCM = 1184212018080
Thus, we can understand that the LCM of 871,458,868,665,288 is 1184212018080.
