Given numbers are 781,781,542,775

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

The LCM of 781,781,542,775 is 328059050.

Find LCM of 781,781,542,775 with Prime Factorization

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

11 x 71 x 1 x 1 x 542 x 775 = 328059050

Therefore, the lowest common multiple of 781,781,542,775 is 328059050.

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 781 x 542 x 775 = 256214118050

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

781 : 1, 11, 71, 781

542 : 1, 2, 271, 542

775 : 1, 5, 25, 31, 155, 775

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,781,542,775, is 1.

Now, the common factors can be found like this.

781:11x 71

781:11x 71

542:2x 271

775:5x 5x 31

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

11x 71 = 781

Therefore, the value for common factors is 781.

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 = 256214118050/(1x781)

LCM = 256214118050/781

LCM = 328059050

Thus, we can understand that the LCM of 781,781,542,775 is 328059050.
