Calculate the LCM of 212,422,345,844

Given numbers are 212,422,345,844

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

The LCM of 212,422,345,844 is 15432540.

Find LCM of 212,422,345,844 with Prime Factorization


2 212, 422, 345, 844
2 106, 211, 345, 422
211 53, 211, 345, 211
53, 1, 345, 1

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

2 x 2 x 211 x 53 x 1 x 345 x 1 = 15432540

Therefore, the lowest common multiple of 212,422,345,844 is 15432540.

LCM Formula to Find Lowest Common Multiple of 212,422,345,844

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.

212 x 422 x 345 x 844 = 26050127520

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.

212 : 1, 2, 4, 53, 106, 212

422 : 1, 2, 211, 422

345 : 1, 3, 5, 15, 23, 69, 115, 345

844 : 1, 2, 4, 211, 422, 844

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,422,345,844, is 1.

Now, the common factors can be found like this.

212:2x 2x 53

422:2x 211

345:3x 5x 23

844:2x 2x 211

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 211 = 1688

Therefore, the value for common factors is 1688.

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 = 26050127520/(1x1688)

LCM = 26050127520/1688

LCM = 15432540

Thus, we can understand that the LCM of 212,422,345,844 is 15432540.
