Calculate the LCM of 861,155,256,871,633

Given numbers are 861,155,256,871,633

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

The LCM of 861,155,256,871,633 is 6278782298880.

Find LCM of 861,155,256,871,633 with Prime Factorization


3 861, 155, 256, 871, 633
287, 155, 256, 871, 211

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

3 x 287 x 155 x 256 x 871 x 211 = 6278782298880

Therefore, the lowest common multiple of 861,155,256,871,633 is 6278782298880.

LCM Formula to Find Lowest Common Multiple of 861,155,256,871,633

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.

861 x 155 x 256 x 871 x 633 = 18836346896640

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.

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

155 : 1, 5, 31, 155

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

871 : 1, 13, 67, 871

633 : 1, 3, 211, 633

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,155,256,871,633, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

155:5x 31

256:2x 2x 2x 2x 2x 2x 2x 2

871:13x 67

633:3x 211

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

3 = 3

Therefore, the value for common factors is 3.

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 = 18836346896640/(1x3)

LCM = 18836346896640/3

LCM = 6278782298880

Thus, we can understand that the LCM of 861,155,256,871,633 is 6278782298880.
