Given numbers are 990,163,310,455,672

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

The LCM of 990,163,310,455,672 is 7283596320.

Find LCM of 990,163,310,455,672 with Prime Factorization

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

2 x 3 x 5 x 7 x 33 x 163 x 31 x 13 x 16 = 7283596320

Therefore, the lowest common multiple of 990,163,310,455,672 is 7283596320.

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 163 x 310 x 455 x 672 = 15295552272000

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

163 : 1, 163

310 : 1, 2, 5, 10, 31, 62, 155, 310

455 : 1, 5, 7, 13, 35, 65, 91, 455

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,163,310,455,672, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

163:163

310:2x 5x 31

455:5x 7x 13

672:2x 2x 2x 2x 2x 3x 7

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

2x 2x 3x 5x 5x 7 = 2100

Therefore, the value for common factors is 2100.

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 = 15295552272000/(1x2100)

LCM = 15295552272000/2100

LCM = 7283596320

Thus, we can understand that the LCM of 990,163,310,455,672 is 7283596320.
