Given numbers are 173,971,638,781

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

The LCM of 173,971,638,781 is 7609293934.

Find LCM of 173,971,638,781 with Prime Factorization

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

11 x 173 x 971 x 58 x 71 = 7609293934

Therefore, the lowest common multiple of 173,971,638,781 is 7609293934.

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.

173 x 971 x 638 x 781 = 83702233274

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.

173 : 1, 173

971 : 1, 971

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

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 173,971,638,781, is 1.

Now, the common factors can be found like this.

173:173

971:971

638:2x 11x 29

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.

11 = 11

Therefore, the value for common factors is 11.

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 = 83702233274/(1x11)

LCM = 83702233274/11

LCM = 7609293934

Thus, we can understand that the LCM of 173,971,638,781 is 7609293934.
