Given numbers are 842,673,638,354

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

The LCM of 842,673,638,354 is 31995662358.

Find LCM of 842,673,638,354 with Prime Factorization

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

2 x 421 x 673 x 319 x 177 = 31995662358

Therefore, the lowest common multiple of 842,673,638,354 is 31995662358.

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.

842 x 673 x 638 x 354 = 127982649432

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.

842 : 1, 2, 421, 842

673 : 1, 673

638 : 1, 2, 11, 22, 29, 58, 319, 638

354 : 1, 2, 3, 6, 59, 118, 177, 354

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,673,638,354, is 1.

Now, the common factors can be found like this.

842:2x 421

673:673

638:2x 11x 29

354:2x 3x 59

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 = 127982649432/(1x4)

LCM = 127982649432/4

LCM = 31995662358

Thus, we can understand that the LCM of 842,673,638,354 is 31995662358.
