Calculate the LCM of 863,861,247,871

Given numbers are 863,861,247,871

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 863,861,247,871 is 12296618607.

Find LCM of 863,861,247,871 with Prime Factorization


13 863, 861, 247, 871
863, 861, 19, 67

Multiply the prime numbers at the bottom and the left side.

13 x 863 x 861 x 19 x 67 = 12296618607

Therefore, the lowest common multiple of 863,861,247,871 is 12296618607.

LCM Formula to Find Lowest Common Multiple of 863,861,247,871

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.

863 x 861 x 247 x 871 = 159856041891

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.

863 : 1, 863

861 : 1, 3, 7, 21, 41, 123, 287, 861

247 : 1, 13, 19, 247

871 : 1, 13, 67, 871

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,861,247,871, is 1.

Now, the common factors can be found like this.

863:863

861:3x 7x 41

247:13x 19

871:13x 67

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

13 = 13

Therefore, the value for common factors is 13.

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 = 159856041891/(1x13)

LCM = 159856041891/13

LCM = 12296618607

Thus, we can understand that the LCM of 863,861,247,871 is 12296618607.
