Given numbers are 287,214,130,854

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

The LCM of 287,214,130,854 is 243522370.

Find LCM of 287,214,130,854 with Prime Factorization

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

2 x 7 x 41 x 107 x 65 x 61 = 243522370

Therefore, the lowest common multiple of 287,214,130,854 is 243522370.

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.

287 x 214 x 130 x 854 = 6818626360

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.

287 : 1, 7, 41, 287

214 : 1, 2, 107, 214

130 : 1, 2, 5, 10, 13, 26, 65, 130

854 : 1, 2, 7, 14, 61, 122, 427, 854

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,214,130,854, is 1.

Now, the common factors can be found like this.

287:7x 41

214:2x 107

130:2x 5x 13

854:2x 7x 61

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 7 = 28

Therefore, the value for common factors is 28.

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 = 6818626360/(1x28)

LCM = 6818626360/28

LCM = 243522370

Thus, we can understand that the LCM of 287,214,130,854 is 243522370.
