Given numbers are 422,858,713,421

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

The LCM of 422,858,713,421 is 54342719574.

Find LCM of 422,858,713,421 with Prime Factorization

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

2 x 211 x 429 x 713 x 421 = 54342719574

Therefore, the lowest common multiple of 422,858,713,421 is 54342719574.

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.

422 x 858 x 713 x 421 = 108685439148

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.

422 : 1, 2, 211, 422

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

713 : 1, 23, 31, 713

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,858,713,421, is 1.

Now, the common factors can be found like this.

422:2x 211

858:2x 3x 11x 13

713:23x 31

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 = 108685439148/(1x2)

LCM = 108685439148/2

LCM = 54342719574

Thus, we can understand that the LCM of 422,858,713,421 is 54342719574.
