Calculate the LCM of 810,551,140,353

Given numbers are 810,551,140,353

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

The LCM of 810,551,140,353 is 2205664020.

Find LCM of 810,551,140,353 with Prime Factorization


2 810, 551, 140, 353
5 405, 551, 70, 353
81, 551, 14, 353

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

2 x 5 x 81 x 551 x 14 x 353 = 2205664020

Therefore, the lowest common multiple of 810,551,140,353 is 2205664020.

LCM Formula to Find Lowest Common Multiple of 810,551,140,353

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.

810 x 551 x 140 x 353 = 22056640200

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.

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

551 : 1, 19, 29, 551

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

353 : 1, 353

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,551,140,353, is 1.

Now, the common factors can be found like this.

810:2x 3x 3x 3x 3x 5

551:19x 29

140:2x 2x 5x 7

353:353

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 22056640200/(1x10)

LCM = 22056640200/10

LCM = 2205664020

Thus, we can understand that the LCM of 810,551,140,353 is 2205664020.
