Given numbers are 641,641,842,853

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

The LCM of 641,641,842,853 is 460382866.

Find LCM of 641,641,842,853 with Prime Factorization

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

641 x 1 x 1 x 842 x 853 = 460382866

Therefore, the lowest common multiple of 641,641,842,853 is 460382866.

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.

641 x 641 x 842 x 853 = 295105417106

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.

641 : 1, 641

641 : 1, 641

842 : 1, 2, 421, 842

853 : 1, 853

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,641,842,853, is 1.

Now, the common factors can be found like this.

641:641

641:641

842:2x 421

853:853

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

641 = 641

Therefore, the value for common factors is 641.

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 = 295105417106/(1x641)

LCM = 295105417106/641

LCM = 460382866

Thus, we can understand that the LCM of 641,641,842,853 is 460382866.
