Calculate the LCM of 261,871,162,386

Given numbers are 261,871,162,386

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

The LCM of 261,871,162,386 is 789747894.

Find LCM of 261,871,162,386 with Prime Factorization


2 261, 871, 162, 386
3 261, 871, 81, 193
3 87, 871, 27, 193
29, 871, 9, 193

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

2 x 3 x 3 x 29 x 871 x 9 x 193 = 789747894

Therefore, the lowest common multiple of 261,871,162,386 is 789747894.

LCM Formula to Find Lowest Common Multiple of 261,871,162,386

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 871 x 162 x 386 = 14215462092

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

871 : 1, 13, 67, 871

162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,871,162,386, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

871:13x 67

162:2x 3x 3x 3x 3

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 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 14215462092/(1x18)

LCM = 14215462092/18

LCM = 789747894

Thus, we can understand that the LCM of 261,871,162,386 is 789747894.
