Given numbers are 730,458,440,660

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

The LCM of 730,458,440,660 is 22066440.

Find LCM of 730,458,440,660 with Prime Factorization

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

2 x 2 x 5 x 11 x 73 x 229 x 2 x 3 = 22066440

Therefore, the lowest common multiple of 730,458,440,660 is 22066440.

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.

730 x 458 x 440 x 660 = 97092336000

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.

730 : 1, 2, 5, 10, 73, 146, 365, 730

458 : 1, 2, 229, 458

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,458,440,660, is 2.

Now, the common factors can be found like this.

730:2x 5x 73

458:2x 229

440:2x 2x 2x 5x 11

660:2x 2x 3x 5x 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 2x 2x 5x 5x 11 = 2200

Therefore, the value for common factors is 2200.

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 = 97092336000/(2x2200)

LCM = 97092336000/4400

LCM = 22066440

Thus, we can understand that the LCM of 730,458,440,660 is 22066440.
