Calculate the LCM of 261,645,734,919,343

Given numbers are 261,645,734,919,343

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

The LCM of 261,645,734,919,343 is 12983287034970.

Find LCM of 261,645,734,919,343 with Prime Factorization


3 261, 645, 734, 919, 343
87, 215, 734, 919, 343

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

3 x 87 x 215 x 734 x 919 x 343 = 12983287034970

Therefore, the lowest common multiple of 261,645,734,919,343 is 12983287034970.

LCM Formula to Find Lowest Common Multiple of 261,645,734,919,343

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.

261 x 645 x 734 x 919 x 343 = 38949861104910

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.

261 : 1, 3, 9, 29, 87, 261

645 : 1, 3, 5, 15, 43, 129, 215, 645

734 : 1, 2, 367, 734

919 : 1, 919

343 : 1, 7, 49, 343

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,645,734,919,343, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

645:3x 5x 43

734:2x 367

919:919

343:7x 7x 7

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

3 = 3

Therefore, the value for common factors is 3.

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 = 38949861104910/(1x3)

LCM = 38949861104910/3

LCM = 12983287034970

Thus, we can understand that the LCM of 261,645,734,919,343 is 12983287034970.
