Calculate the LCM of 361,494,699,405,381

Given numbers are 361,494,699,405,381

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

The LCM of 361,494,699,405,381 is 112485156030.

Find LCM of 361,494,699,405,381 with Prime Factorization


3 361, 494, 699, 405, 381
19 361, 494, 233, 135, 127
19, 26, 233, 135, 127

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

3 x 19 x 19 x 26 x 233 x 135 x 127 = 112485156030

Therefore, the lowest common multiple of 361,494,699,405,381 is 112485156030.

LCM Formula to Find Lowest Common Multiple of 361,494,699,405,381

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.

361 x 494 x 699 x 405 x 381 = 19234961681130

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.

361 : 1, 19, 361

494 : 1, 2, 13, 19, 26, 38, 247, 494

699 : 1, 3, 233, 699

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,494,699,405,381, is 1.

Now, the common factors can be found like this.

361:19x 19

494:2x 13x 19

699:3x 233

405:3x 3x 3x 3x 5

381:3x 127

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 19 = 171

Therefore, the value for common factors is 171.

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 = 19234961681130/(1x171)

LCM = 19234961681130/171

LCM = 112485156030

Thus, we can understand that the LCM of 361,494,699,405,381 is 112485156030.
