Given numbers are 130,646,409,670

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

The LCM of 130,646,409,670 is 1150651970.

Find LCM of 130,646,409,670 with Prime Factorization

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

2 x 5 x 13 x 323 x 409 x 67 = 1150651970

Therefore, the lowest common multiple of 130,646,409,670 is 1150651970.

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 646 x 409 x 670 = 23013039400

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

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

409 : 1, 409

670 : 1, 2, 5, 10, 67, 134, 335, 670

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,646,409,670, is 1.

Now, the common factors can be found like this.

130:2x 5x 13

646:2x 17x 19

409:409

670:2x 5x 67

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 5 = 20

Therefore, the value for common factors is 20.

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 = 23013039400/(1x20)

LCM = 23013039400/20

LCM = 1150651970

Thus, we can understand that the LCM of 130,646,409,670 is 1150651970.
