Given numbers are 130,274,646,478

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

The LCM of 130,274,646,478 is 1374878570.

Find LCM of 130,274,646,478 with Prime Factorization

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

2 x 65 x 137 x 323 x 239 = 1374878570

Therefore, the lowest common multiple of 130,274,646,478 is 1374878570.

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 274 x 646 x 478 = 10999028560

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

274 : 1, 2, 137, 274

646 : 1, 2, 17, 19, 34, 38, 323, 646

478 : 1, 2, 239, 478

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,274,646,478, is 2.

Now, the common factors can be found like this.

130:2x 5x 13

274:2x 137

646:2x 17x 19

478:2x 239

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 = 10999028560/(2x4)

LCM = 10999028560/8

LCM = 1374878570

Thus, we can understand that the LCM of 130,274,646,478 is 1374878570.
