Calculate the LCM of 187,731,895,646

Given numbers are 187,731,895,646

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

The LCM of 187,731,895,646 is 273474410.

Find LCM of 187,731,895,646 with Prime Factorization


17 187, 731, 895, 646
11, 43, 895, 38

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

17 x 11 x 43 x 895 x 38 = 273474410

Therefore, the lowest common multiple of 187,731,895,646 is 273474410.

LCM Formula to Find Lowest Common Multiple of 187,731,895,646

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.

187 x 731 x 895 x 646 = 79034104490

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.

187 : 1, 11, 17, 187

731 : 1, 17, 43, 731

895 : 1, 5, 179, 895

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,731,895,646, is 1.

Now, the common factors can be found like this.

187:11x 17

731:17x 43

895:5x 179

646:2x 17x 19

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

17x 17 = 289

Therefore, the value for common factors is 289.

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 = 79034104490/(1x289)

LCM = 79034104490/289

LCM = 273474410

Thus, we can understand that the LCM of 187,731,895,646 is 273474410.
