Calculate the LCM of 422,861,961,478

Given numbers are 422,861,961,478

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

The LCM of 422,861,961,478 is 83452027218.

Find LCM of 422,861,961,478 with Prime Factorization


2 422, 861, 961, 478
211, 861, 961, 239

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

2 x 211 x 861 x 961 x 239 = 83452027218

Therefore, the lowest common multiple of 422,861,961,478 is 83452027218.

LCM Formula to Find Lowest Common Multiple of 422,861,961,478

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.

422 x 861 x 961 x 478 = 166904054436

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.

422 : 1, 2, 211, 422

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

961 : 1, 31, 961

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,861,961,478, is 1.

Now, the common factors can be found like this.

422:2x 211

861:3x 7x 41

961:31x 31

478:2x 239

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

2 = 2

Therefore, the value for common factors is 2.

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 = 166904054436/(1x2)

LCM = 166904054436/2

LCM = 83452027218

Thus, we can understand that the LCM of 422,861,961,478 is 83452027218.
