Given numbers are 198,417,161,754

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

The LCM of 198,417,161,754 is 1670502834.

Find LCM of 198,417,161,754 with Prime Factorization

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

2 x 3 x 33 x 139 x 161 x 377 = 1670502834

Therefore, the lowest common multiple of 198,417,161,754 is 1670502834.

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 417 x 161 x 754 = 10023017004

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

417 : 1, 3, 139, 417

161 : 1, 7, 23, 161

754 : 1, 2, 13, 26, 29, 58, 377, 754

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,417,161,754, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

417:3x 139

161:7x 23

754:2x 13x 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 3 = 6

Therefore, the value for common factors is 6.

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 = 10023017004/(1x6)

LCM = 10023017004/6

LCM = 1670502834

Thus, we can understand that the LCM of 198,417,161,754 is 1670502834.
