Given numbers are 194,412,638,289

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

The LCM of 194,412,638,289 is 3684321124.

Find LCM of 194,412,638,289 with Prime Factorization

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

2 x 97 x 206 x 319 x 289 = 3684321124

Therefore, the lowest common multiple of 194,412,638,289 is 3684321124.

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.

194 x 412 x 638 x 289 = 14737284496

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.

194 : 1, 2, 97, 194

412 : 1, 2, 4, 103, 206, 412

638 : 1, 2, 11, 22, 29, 58, 319, 638

289 : 1, 17, 289

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,412,638,289, is 1.

Now, the common factors can be found like this.

194:2x 97

412:2x 2x 103

638:2x 11x 29

289:17x 17

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 14737284496/(1x4)

LCM = 14737284496/4

LCM = 3684321124

Thus, we can understand that the LCM of 194,412,638,289 is 3684321124.
