Given numbers are 781,213,410,923

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

The LCM of 781,213,410,923 is 12488190.

Find LCM of 781,213,410,923 with Prime Factorization

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

71 x 11 x 3 x 410 x 13 = 12488190

Therefore, the lowest common multiple of 781,213,410,923 is 12488190.

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 213 x 410 x 923 = 62952965790

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

213 : 1, 3, 71, 213

410 : 1, 2, 5, 10, 41, 82, 205, 410

923 : 1, 13, 71, 923

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,213,410,923, is 1.

Now, the common factors can be found like this.

781:11x 71

213:3x 71

410:2x 5x 41

923:13x 71

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

71x 71 = 5041

Therefore, the value for common factors is 5041.

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 = 62952965790/(1x5041)

LCM = 62952965790/5041

LCM = 12488190

Thus, we can understand that the LCM of 781,213,410,923 is 12488190.
