Given numbers are 863,641,940,641

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

The LCM of 863,641,940,641 is 519992020.

Find LCM of 863,641,940,641 with Prime Factorization

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

641 x 863 x 1 x 940 x 1 = 519992020

Therefore, the lowest common multiple of 863,641,940,641 is 519992020.

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.

863 x 641 x 940 x 641 = 333314884820

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.

863 : 1, 863

641 : 1, 641

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 863,641,940,641, is 1.

Now, the common factors can be found like this.

863:863

641:641

940:2x 2x 5x 47

641:641

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 = 333314884820/(1x641)

LCM = 333314884820/641

LCM = 519992020

Thus, we can understand that the LCM of 863,641,940,641 is 519992020.
