Calculate the LCM of 810,393,861,533

Given numbers are 810,393,861,533

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

The LCM of 810,393,861,533 is 395896410.

Find LCM of 810,393,861,533 with Prime Factorization


3 810, 393, 861, 533
41 270, 131, 287, 533
270, 131, 7, 13

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

3 x 41 x 270 x 131 x 7 x 13 = 395896410

Therefore, the lowest common multiple of 810,393,861,533 is 395896410.

LCM Formula to Find Lowest Common Multiple of 810,393,861,533

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 393 x 861 x 533 = 146085775290

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

393 : 1, 3, 131, 393

861 : 1, 3, 7, 21, 41, 123, 287, 861

533 : 1, 13, 41, 533

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,393,861,533, is 1.

Now, the common factors can be found like this.

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

393:3x 131

861:3x 7x 41

533:13x 41

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

3x 3x 41 = 369

Therefore, the value for common factors is 369.

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 = 146085775290/(1x369)

LCM = 146085775290/369

LCM = 395896410

Thus, we can understand that the LCM of 810,393,861,533 is 395896410.
