Calculate the LCM of 903,861,231,948

Given numbers are 903,861,231,948

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

The LCM of 903,861,231,948 is 128691948.

Find LCM of 903,861,231,948 with Prime Factorization


3 903, 861, 231, 948
7 301, 287, 77, 316
43, 41, 11, 316

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

3 x 7 x 43 x 41 x 11 x 316 = 128691948

Therefore, the lowest common multiple of 903,861,231,948 is 128691948.

LCM Formula to Find Lowest Common Multiple of 903,861,231,948

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.

903 x 861 x 231 x 948 = 170259447204

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.

903 : 1, 3, 7, 21, 43, 129, 301, 903

861 : 1, 3, 7, 21, 41, 123, 287, 861

231 : 1, 3, 7, 11, 21, 33, 77, 231

948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,861,231,948, is 3.

Now, the common factors can be found like this.

903:3x 7x 43

861:3x 7x 41

231:3x 7x 11

948:2x 2x 3x 79

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

3x 3x 7x 7 = 441

Therefore, the value for common factors is 441.

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 = 170259447204/(3x441)

LCM = 170259447204/1323

LCM = 128691948

Thus, we can understand that the LCM of 903,861,231,948 is 128691948.
