Given numbers are 641,821,473,552,747

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

The LCM of 641,821,473,552,747 is 34213755871944.

Find LCM of 641,821,473,552,747 with Prime Factorization

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

3 x 641 x 821 x 473 x 184 x 249 = 34213755871944

Therefore, the lowest common multiple of 641,821,473,552,747 is 34213755871944.

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 821 x 473 x 552 x 747 = 102641267615832

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

821 : 1, 821

473 : 1, 11, 43, 473

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

747 : 1, 3, 9, 83, 249, 747

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,821,473,552,747, is 1.

Now, the common factors can be found like this.

641:641

821:821

473:11x 43

552:2x 2x 2x 3x 23

747:3x 3x 83

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

3 = 3

Therefore, the value for common factors is 3.

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 = 102641267615832/(1x3)

LCM = 102641267615832/3

LCM = 34213755871944

Thus, we can understand that the LCM of 641,821,473,552,747 is 34213755871944.
