Given numbers are 198,397,861,741

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

The LCM of 198,397,861,741 is 5572300734.

Find LCM of 198,397,861,741 with Prime Factorization

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

3 x 66 x 397 x 287 x 247 = 5572300734

Therefore, the lowest common multiple of 198,397,861,741 is 5572300734.

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 397 x 861 x 741 = 50150706606

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

397 : 1, 397

861 : 1, 3, 7, 21, 41, 123, 287, 861

741 : 1, 3, 13, 19, 39, 57, 247, 741

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,397,861,741, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

397:397

861:3x 7x 41

741:3x 13x 19

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 50150706606/(1x9)

LCM = 50150706606/9

LCM = 5572300734

Thus, we can understand that the LCM of 198,397,861,741 is 5572300734.
