Calculate the LCM of 815,794,794,221

Given numbers are 815,794,794,221

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

The LCM of 815,794,794,221 is 143011310.

Find LCM of 815,794,794,221 with Prime Factorization


2 815, 794, 794, 221
397 815, 397, 397, 221
815, 1, 1, 221

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

2 x 397 x 815 x 1 x 1 x 221 = 143011310

Therefore, the lowest common multiple of 815,794,794,221 is 143011310.

LCM Formula to Find Lowest Common Multiple of 815,794,794,221

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.

815 x 794 x 794 x 221 = 113550980140

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.

815 : 1, 5, 163, 815

794 : 1, 2, 397, 794

794 : 1, 2, 397, 794

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,794,794,221, is 1.

Now, the common factors can be found like this.

815:5x 163

794:2x 397

794:2x 397

221:13x 17

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

2x 397 = 794

Therefore, the value for common factors is 794.

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 = 113550980140/(1x794)

LCM = 113550980140/794

LCM = 143011310

Thus, we can understand that the LCM of 815,794,794,221 is 143011310.
