Given numbers are 815,343,242,902

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

The LCM of 815,343,242,902 is 2773645490.

Find LCM of 815,343,242,902 with Prime Factorization

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

2 x 11 x 815 x 343 x 11 x 41 = 2773645490

Therefore, the lowest common multiple of 815,343,242,902 is 2773645490.

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 343 x 242 x 902 = 61020200780

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

343 : 1, 7, 49, 343

242 : 1, 2, 11, 22, 121, 242

902 : 1, 2, 11, 22, 41, 82, 451, 902

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,343,242,902, is 1.

Now, the common factors can be found like this.

815:5x 163

343:7x 7x 7

242:2x 11x 11

902:2x 11x 41

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 61020200780/(1x22)

LCM = 61020200780/22

LCM = 2773645490

Thus, we can understand that the LCM of 815,343,242,902 is 2773645490.
