Calculate the LCM of 261,660,390,386

Given numbers are 261,660,390,386

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

The LCM of 261,660,390,386 is 144066780.

Find LCM of 261,660,390,386 with Prime Factorization


2 261, 660, 390, 386
3 261, 330, 195, 193
5 87, 110, 65, 193
87, 22, 13, 193

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

2 x 3 x 5 x 87 x 22 x 13 x 193 = 144066780

Therefore, the lowest common multiple of 261,660,390,386 is 144066780.

LCM Formula to Find Lowest Common Multiple of 261,660,390,386

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 660 x 390 x 386 = 25932020400

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

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

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

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,660,390,386, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

660:2x 2x 3x 5x 11

390:2x 3x 5x 13

386:2x 193

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 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 25932020400/(1x180)

LCM = 25932020400/180

LCM = 144066780

Thus, we can understand that the LCM of 261,660,390,386 is 144066780.
