Given numbers are 856,131,386,181

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

The LCM of 856,131,386,181 is 3917246888.

Find LCM of 856,131,386,181 with Prime Factorization

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

2 x 428 x 131 x 193 x 181 = 3917246888

Therefore, the lowest common multiple of 856,131,386,181 is 3917246888.

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.

856 x 131 x 386 x 181 = 7834493776

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

131 : 1, 131

386 : 1, 2, 193, 386

181 : 1, 181

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,131,386,181, is 1.

Now, the common factors can be found like this.

856:2x 2x 2x 107

131:131

386:2x 193

181:181

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

2 = 2

Therefore, the value for common factors is 2.

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 = 7834493776/(1x2)

LCM = 7834493776/2

LCM = 3917246888

Thus, we can understand that the LCM of 856,131,386,181 is 3917246888.
