Given numbers are 815,442,603,354,129

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

The LCM of 815,442,603,354,129 is 551083816530.

Find LCM of 815,442,603,354,129 with Prime Factorization

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

2 x 3 x 815 x 221 x 201 x 59 x 43 = 551083816530

Therefore, the lowest common multiple of 815,442,603,354,129 is 551083816530.

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 442 x 603 x 354 x 129 = 9919508697540

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

442 : 1, 2, 13, 17, 26, 34, 221, 442

603 : 1, 3, 9, 67, 201, 603

354 : 1, 2, 3, 6, 59, 118, 177, 354

129 : 1, 3, 43, 129

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,442,603,354,129, is 1.

Now, the common factors can be found like this.

815:5x 163

442:2x 13x 17

603:3x 3x 67

354:2x 3x 59

129:3x 43

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 9919508697540/(1x18)

LCM = 9919508697540/18

LCM = 551083816530

Thus, we can understand that the LCM of 815,442,603,354,129 is 551083816530.
