Given numbers are 198,253,793,745,781

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

The LCM of 198,253,793,745,781 is 191020877190.

Find LCM of 198,253,793,745,781 with Prime Factorization

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

11 x 18 x 23 x 793 x 745 x 71 = 191020877190

Therefore, the lowest common multiple of 198,253,793,745,781 is 191020877190.

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 253 x 793 x 745 x 781 = 23113526139990

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

253 : 1, 11, 23, 253

793 : 1, 13, 61, 793

745 : 1, 5, 149, 745

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,253,793,745,781, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

253:11x 23

793:13x 61

745:5x 149

781:11x 71

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 23113526139990/(1x121)

LCM = 23113526139990/121

LCM = 191020877190

Thus, we can understand that the LCM of 198,253,793,745,781 is 191020877190.
