Calculate the LCM of 818,212,609,390

Given numbers are 818,212,609,390

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

The LCM of 818,212,609,390 is 3432336180.

Find LCM of 818,212,609,390 with Prime Factorization


2 818, 212, 609, 390
3 409, 106, 609, 195
409, 106, 203, 65

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

2 x 3 x 409 x 106 x 203 x 65 = 3432336180

Therefore, the lowest common multiple of 818,212,609,390 is 3432336180.

LCM Formula to Find Lowest Common Multiple of 818,212,609,390

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.

818 x 212 x 609 x 390 = 41188034160

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.

818 : 1, 2, 409, 818

212 : 1, 2, 4, 53, 106, 212

609 : 1, 3, 7, 21, 29, 87, 203, 609

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,212,609,390, is 1.

Now, the common factors can be found like this.

818:2x 409

212:2x 2x 53

609:3x 7x 29

390:2x 3x 5x 13

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 41188034160/(1x12)

LCM = 41188034160/12

LCM = 3432336180

Thus, we can understand that the LCM of 818,212,609,390 is 3432336180.
