Calculate the LCM of 815,121,408,473

Given numbers are 815,121,408,473

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

The LCM of 815,121,408,473 is 1730101560.

Find LCM of 815,121,408,473 with Prime Factorization


11 815, 121, 408, 473
815, 11, 408, 43

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

11 x 815 x 11 x 408 x 43 = 1730101560

Therefore, the lowest common multiple of 815,121,408,473 is 1730101560.

LCM Formula to Find Lowest Common Multiple of 815,121,408,473

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 121 x 408 x 473 = 19031117160

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

121 : 1, 11, 121

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

473 : 1, 11, 43, 473

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,121,408,473, is 1.

Now, the common factors can be found like this.

815:5x 163

121:11x 11

408:2x 2x 2x 3x 17

473:11x 43

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

11 = 11

Therefore, the value for common factors is 11.

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 = 19031117160/(1x11)

LCM = 19031117160/11

LCM = 1730101560

Thus, we can understand that the LCM of 815,121,408,473 is 1730101560.
