Given numbers are 781,627,190,173

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

The LCM of 781,627,190,173 is 77014410.

Find LCM of 781,627,190,173 with Prime Factorization

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

11 x 19 x 71 x 3 x 10 x 173 = 77014410

Therefore, the lowest common multiple of 781,627,190,173 is 77014410.

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.

781 x 627 x 190 x 173 = 16096011690

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.

781 : 1, 11, 71, 781

627 : 1, 3, 11, 19, 33, 57, 209, 627

190 : 1, 2, 5, 10, 19, 38, 95, 190

173 : 1, 173

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,627,190,173, is 1.

Now, the common factors can be found like this.

781:11x 71

627:3x 11x 19

190:2x 5x 19

173:173

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

11x 19 = 209

Therefore, the value for common factors is 209.

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 = 16096011690/(1x209)

LCM = 16096011690/209

LCM = 77014410

Thus, we can understand that the LCM of 781,627,190,173 is 77014410.
