Given numbers are 787,678,808,421

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

The LCM of 787,678,808,421 is 90754441224.

Find LCM of 787,678,808,421 with Prime Factorization

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

2 x 787 x 339 x 404 x 421 = 90754441224

Therefore, the lowest common multiple of 787,678,808,421 is 90754441224.

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.

787 x 678 x 808 x 421 = 181508882448

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.

787 : 1, 787

678 : 1, 2, 3, 6, 113, 226, 339, 678

808 : 1, 2, 4, 8, 101, 202, 404, 808

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,678,808,421, is 1.

Now, the common factors can be found like this.

787:787

678:2x 3x 113

808:2x 2x 2x 101

421:421

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

2 = 2

Therefore, the value for common factors is 2.

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 = 181508882448/(1x2)

LCM = 181508882448/2

LCM = 90754441224

Thus, we can understand that the LCM of 787,678,808,421 is 90754441224.
