Calculate the LCM of 407,681,195,845

Given numbers are 407,681,195,845

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

The LCM of 407,681,195,845 is 234206115.

Find LCM of 407,681,195,845 with Prime Factorization


3 407, 681, 195, 845
5 407, 227, 65, 845
13 407, 227, 13, 169
407, 227, 1, 13

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

3 x 5 x 13 x 407 x 227 x 1 x 13 = 234206115

Therefore, the lowest common multiple of 407,681,195,845 is 234206115.

LCM Formula to Find Lowest Common Multiple of 407,681,195,845

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.

407 x 681 x 195 x 845 = 45670192425

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.

407 : 1, 11, 37, 407

681 : 1, 3, 227, 681

195 : 1, 3, 5, 13, 15, 39, 65, 195

845 : 1, 5, 13, 65, 169, 845

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,681,195,845, is 1.

Now, the common factors can be found like this.

407:11x 37

681:3x 227

195:3x 5x 13

845:5x 13x 13

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

3x 5x 13 = 195

Therefore, the value for common factors is 195.

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 = 45670192425/(1x195)

LCM = 45670192425/195

LCM = 234206115

Thus, we can understand that the LCM of 407,681,195,845 is 234206115.
