Given numbers are 990,703,707,815,870

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

The LCM of 990,703,707,815,870 is 2325924084330.

Find LCM of 990,703,707,815,870 with Prime Factorization

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

2 x 3 x 5 x 33 x 703 x 707 x 163 x 29 = 2325924084330

Therefore, the lowest common multiple of 990,703,707,815,870 is 2325924084330.

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.

990 x 703 x 707 x 815 x 870 = 348888612649500

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.

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

703 : 1, 19, 37, 703

707 : 1, 7, 101, 707

815 : 1, 5, 163, 815

870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,703,707,815,870, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

703:19x 37

707:7x 101

815:5x 163

870:2x 3x 5x 29

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

2x 3x 5x 5 = 150

Therefore, the value for common factors is 150.

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 = 348888612649500/(1x150)

LCM = 348888612649500/150

LCM = 2325924084330

Thus, we can understand that the LCM of 990,703,707,815,870 is 2325924084330.
