Calculate the LCM of 261,309,669,896

Given numbers are 261,309,669,896

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

The LCM of 261,309,669,896 is 5371438464.

Find LCM of 261,309,669,896 with Prime Factorization


3 261, 309, 669, 896
87, 103, 223, 896

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

3 x 87 x 103 x 223 x 896 = 5371438464

Therefore, the lowest common multiple of 261,309,669,896 is 5371438464.

LCM Formula to Find Lowest Common Multiple of 261,309,669,896

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 309 x 669 x 896 = 48342946176

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

309 : 1, 3, 103, 309

669 : 1, 3, 223, 669

896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,309,669,896, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

309:3x 103

669:3x 223

896:2x 2x 2x 2x 2x 2x 2x 7

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 48342946176/(1x9)

LCM = 48342946176/9

LCM = 5371438464

Thus, we can understand that the LCM of 261,309,669,896 is 5371438464.
