Given numbers are 489,670,321,442

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

The LCM of 489,670,321,442 is 7747466610.

Find LCM of 489,670,321,442 with Prime Factorization

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

2 x 3 x 163 x 335 x 107 x 221 = 7747466610

Therefore, the lowest common multiple of 489,670,321,442 is 7747466610.

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.

489 x 670 x 321 x 442 = 46484799660

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.

489 : 1, 3, 163, 489

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

321 : 1, 3, 107, 321

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,670,321,442, is 1.

Now, the common factors can be found like this.

489:3x 163

670:2x 5x 67

321:3x 107

442:2x 13x 17

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 46484799660/(1x6)

LCM = 46484799660/6

LCM = 7747466610

Thus, we can understand that the LCM of 489,670,321,442 is 7747466610.
