Given numbers are 990,803,247,854

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

The LCM of 990,803,247,854 is 7622244630.

Find LCM of 990,803,247,854 with Prime Factorization

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

2 x 11 x 45 x 73 x 247 x 427 = 7622244630

Therefore, the lowest common multiple of 990,803,247,854 is 7622244630.

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 803 x 247 x 854 = 167689381860

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

803 : 1, 11, 73, 803

247 : 1, 13, 19, 247

854 : 1, 2, 7, 14, 61, 122, 427, 854

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,803,247,854, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

803:11x 73

247:13x 19

854:2x 7x 61

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 167689381860/(1x22)

LCM = 167689381860/22

LCM = 7622244630

Thus, we can understand that the LCM of 990,803,247,854 is 7622244630.
