Given numbers are 130,321,115,685

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

The LCM of 130,321,115,685 is 131491230.

Find LCM of 130,321,115,685 with Prime Factorization

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

5 x 26 x 321 x 23 x 137 = 131491230

Therefore, the lowest common multiple of 130,321,115,685 is 131491230.

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.

130 x 321 x 115 x 685 = 3287280750

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.

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

321 : 1, 3, 107, 321

115 : 1, 5, 23, 115

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,321,115,685, is 1.

Now, the common factors can be found like this.

130:2x 5x 13

321:3x 107

115:5x 23

685:5x 137

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 3287280750/(1x25)

LCM = 3287280750/25

LCM = 131491230

Thus, we can understand that the LCM of 130,321,115,685 is 131491230.
