Given numbers are 130,194,643,308

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

The LCM of 130,194,643,308 is 1248667420.

Find LCM of 130,194,643,308 with Prime Factorization

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

2 x 65 x 97 x 643 x 154 = 1248667420

Therefore, the lowest common multiple of 130,194,643,308 is 1248667420.

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 194 x 643 x 308 = 4994669680

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

194 : 1, 2, 97, 194

643 : 1, 643

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,194,643,308, is 1.

Now, the common factors can be found like this.

130:2x 5x 13

194:2x 97

643:643

308:2x 2x 7x 11

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 4994669680/(1x4)

LCM = 4994669680/4

LCM = 1248667420

Thus, we can understand that the LCM of 130,194,643,308 is 1248667420.
