Given numbers are 130,681,949,221

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

The LCM of 130,681,949,221 is 109865730.

Find LCM of 130,681,949,221 with Prime Factorization

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

13 x 10 x 681 x 73 x 17 = 109865730

Therefore, the lowest common multiple of 130,681,949,221 is 109865730.

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 681 x 949 x 221 = 18567308370

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

681 : 1, 3, 227, 681

949 : 1, 13, 73, 949

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,681,949,221, is 1.

Now, the common factors can be found like this.

130:2x 5x 13

681:3x 227

949:13x 73

221:13x 17

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 18567308370/(1x169)

LCM = 18567308370/169

LCM = 109865730

Thus, we can understand that the LCM of 130,681,949,221 is 109865730.
