Given numbers are 814,840,787,514

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

The LCM of 814,840,787,514 is 69148306920.

Find LCM of 814,840,787,514 with Prime Factorization

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

2 x 407 x 420 x 787 x 257 = 69148306920

Therefore, the lowest common multiple of 814,840,787,514 is 69148306920.

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.

814 x 840 x 787 x 514 = 276593227680

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.

814 : 1, 2, 11, 22, 37, 74, 407, 814

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

787 : 1, 787

514 : 1, 2, 257, 514

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,840,787,514, is 1.

Now, the common factors can be found like this.

814:2x 11x 37

840:2x 2x 2x 3x 5x 7

787:787

514:2x 257

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 276593227680/(1x4)

LCM = 276593227680/4

LCM = 69148306920

Thus, we can understand that the LCM of 814,840,787,514 is 69148306920.
