Given numbers are 861,283,720,542,716

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

The LCM of 861,283,720,542,716 is 2836763632080.

Find LCM of 861,283,720,542,716 with Prime Factorization

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

2 x 2 x 3 x 287 x 283 x 60 x 271 x 179 = 2836763632080

Therefore, the lowest common multiple of 861,283,720,542,716 is 2836763632080.

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.

861 x 283 x 720 x 542 x 716 = 68082327169920

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

283 : 1, 283

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

542 : 1, 2, 271, 542

716 : 1, 2, 4, 179, 358, 716

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,283,720,542,716, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

283:283

720:2x 2x 2x 2x 3x 3x 5

542:2x 271

716:2x 2x 179

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

2x 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 68082327169920/(1x24)

LCM = 68082327169920/24

LCM = 2836763632080

Thus, we can understand that the LCM of 861,283,720,542,716 is 2836763632080.
