Given numbers are 677,642,724,641,394

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

The LCM of 677,642,724,641,394 is 19868108497716.

Find LCM of 677,642,724,641,394 with Prime Factorization

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

2 x 677 x 321 x 362 x 641 x 197 = 19868108497716

Therefore, the lowest common multiple of 677,642,724,641,394 is 19868108497716.

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.

677 x 642 x 724 x 641 x 394 = 79472433990864

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.

677 : 1, 677

642 : 1, 2, 3, 6, 107, 214, 321, 642

724 : 1, 2, 4, 181, 362, 724

641 : 1, 641

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,642,724,641,394, is 1.

Now, the common factors can be found like this.

677:677

642:2x 3x 107

724:2x 2x 181

641:641

394:2x 197

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 79472433990864/(1x4)

LCM = 79472433990864/4

LCM = 19868108497716

Thus, we can understand that the LCM of 677,642,724,641,394 is 19868108497716.
