Given numbers are 489,624,673,915

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

The LCM of 489,624,673,915 is 20877913680.

Find LCM of 489,624,673,915 with Prime Factorization

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

3 x 163 x 208 x 673 x 305 = 20877913680

Therefore, the lowest common multiple of 489,624,673,915 is 20877913680.

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 624 x 673 x 915 = 187901223120

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

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

673 : 1, 673

915 : 1, 3, 5, 15, 61, 183, 305, 915

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,624,673,915, is 1.

Now, the common factors can be found like this.

489:3x 163

624:2x 2x 2x 2x 3x 13

673:673

915:3x 5x 61

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 187901223120/(1x9)

LCM = 187901223120/9

LCM = 20877913680

Thus, we can understand that the LCM of 489,624,673,915 is 20877913680.
