Calculate the LCM of 289,871,871,945

Given numbers are 289,871,871,945

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

The LCM of 289,871,871,945 is 237874455.

Find LCM of 289,871,871,945 with Prime Factorization


13 289, 871, 871, 945
67 289, 67, 67, 945
289, 1, 1, 945

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

13 x 67 x 289 x 1 x 1 x 945 = 237874455

Therefore, the lowest common multiple of 289,871,871,945 is 237874455.

LCM Formula to Find Lowest Common Multiple of 289,871,871,945

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.

289 x 871 x 871 x 945 = 207188650305

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.

289 : 1, 17, 289

871 : 1, 13, 67, 871

871 : 1, 13, 67, 871

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,871,871,945, is 1.

Now, the common factors can be found like this.

289:17x 17

871:13x 67

871:13x 67

945:3x 3x 3x 5x 7

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

13x 67 = 871

Therefore, the value for common factors is 871.

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 = 207188650305/(1x871)

LCM = 207188650305/871

LCM = 237874455

Thus, we can understand that the LCM of 289,871,871,945 is 237874455.
