Given numbers are 130,260,631,970

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

The LCM of 130,260,631,970 is 15913820.

Find LCM of 130,260,631,970 with Prime Factorization

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

2 x 5 x 13 x 1 x 2 x 631 x 97 = 15913820

Therefore, the lowest common multiple of 130,260,631,970 is 15913820.

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 260 x 631 x 970 = 20687966000

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

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

631 : 1, 631

970 : 1, 2, 5, 10, 97, 194, 485, 970

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,260,631,970, is 1.

Now, the common factors can be found like this.

130:2x 5x 13

260:2x 2x 5x 13

631:631

970:2x 5x 97

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 5x 5x 13 = 1300

Therefore, the value for common factors is 1300.

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 = 20687966000/(1x1300)

LCM = 20687966000/1300

LCM = 15913820

Thus, we can understand that the LCM of 130,260,631,970 is 15913820.

Here are some samples of LCM of two or more Numbers calculations.
