Calculate the LCM of 385,858,898,972

Given numbers are 385,858,898,972

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

The LCM of 385,858,898,972 is 2184322140.

Find LCM of 385,858,898,972 with Prime Factorization


2 385, 858, 898, 972
3 385, 429, 449, 486
11 385, 143, 449, 162
35, 13, 449, 162

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

2 x 3 x 11 x 35 x 13 x 449 x 162 = 2184322140

Therefore, the lowest common multiple of 385,858,898,972 is 2184322140.

LCM Formula to Find Lowest Common Multiple of 385,858,898,972

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.

385 x 858 x 898 x 972 = 288330522480

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.

385 : 1, 5, 7, 11, 35, 55, 77, 385

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

898 : 1, 2, 449, 898

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,858,898,972, is 1.

Now, the common factors can be found like this.

385:5x 7x 11

858:2x 3x 11x 13

898:2x 449

972:2x 2x 3x 3x 3x 3x 3

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 11 = 132

Therefore, the value for common factors is 132.

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 = 288330522480/(1x132)

LCM = 288330522480/132

LCM = 2184322140

Thus, we can understand that the LCM of 385,858,898,972 is 2184322140.
