Given numbers are 781,923,717,57

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

The LCM of 781,923,717,57 is 138314319.

Find LCM of 781,923,717,57 with Prime Factorization

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

3 x 71 x 11 x 13 x 239 x 19 = 138314319

Therefore, the lowest common multiple of 781,923,717,57 is 138314319.

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 923 x 717 x 57 = 29460949947

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

923 : 1, 13, 71, 923

717 : 1, 3, 239, 717

57 : 1, 3, 19, 57

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,923,717,57, is 1.

Now, the common factors can be found like this.

781:11x 71

923:13x 71

717:3x 239

57:3x 19

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

3x 71 = 213

Therefore, the value for common factors is 213.

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 = 29460949947/(1x213)

LCM = 29460949947/213

LCM = 138314319

Thus, we can understand that the LCM of 781,923,717,57 is 138314319.
