Given numbers are 489,703,780

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

The LCM of 489,703,780 is 89379420.

Find LCM of 489,703,780 with Prime Factorization

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

3 x 163 x 703 x 260 = 89379420

Therefore, the lowest common multiple of 489,703,780 is 89379420.

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 703 x 780 = 268138260

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

703 : 1, 19, 37, 703

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,703,780, is 1.

Now, the common factors can be found like this.

489:3x 163

703:19x 37

780:2x 2x 3x 5x 13

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

3 = 3

Therefore, the value for common factors is 3.

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 = 268138260/(1x3)

LCM = 268138260/3

LCM = 89379420

Thus, we can understand that the LCM of 489,703,780 is 89379420.

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

• LCM of 872, 293, 527
