Given numbers are 198,816,787,310,161

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

The LCM of 198,816,787,310,161 is 528854744880.

Find LCM of 198,816,787,310,161 with Prime Factorization

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

2 x 3 x 33 x 136 x 787 x 155 x 161 = 528854744880

Therefore, the lowest common multiple of 198,816,787,310,161 is 528854744880.

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.

198 x 816 x 787 x 310 x 161 = 6346256938560

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.

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

787 : 1, 787

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

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,816,787,310,161, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

816:2x 2x 2x 2x 3x 17

787:787

310:2x 5x 31

161:7x 23

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 3 = 12

Therefore, the value for common factors is 12.

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 = 6346256938560/(1x12)

LCM = 6346256938560/12

LCM = 528854744880

Thus, we can understand that the LCM of 198,816,787,310,161 is 528854744880.
