Given numbers are 641,662,378,409,943

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

The LCM of 641,662,378,409,943 is 30932343468306.

Find LCM of 641,662,378,409,943 with Prime Factorization

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

2 x 641 x 331 x 189 x 409 x 943 = 30932343468306

Therefore, the lowest common multiple of 641,662,378,409,943 is 30932343468306.

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 662 x 378 x 409 x 943 = 61864686936612

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

662 : 1, 2, 331, 662

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

409 : 1, 409

943 : 1, 23, 41, 943

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,662,378,409,943, is 1.

Now, the common factors can be found like this.

641:641

662:2x 331

378:2x 3x 3x 3x 7

409:409

943:23x 41

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 = 61864686936612/(1x2)

LCM = 61864686936612/2

LCM = 30932343468306

Thus, we can understand that the LCM of 641,662,378,409,943 is 30932343468306.
