Given numbers are 943,145,851,638

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

The LCM of 943,145,851,638 is 111302290.

Find LCM of 943,145,851,638 with Prime Factorization

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

23 x 29 x 41 x 5 x 37 x 22 = 111302290

Therefore, the lowest common multiple of 943,145,851,638 is 111302290.

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.

943 x 145 x 851 x 638 = 74238627430

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.

943 : 1, 23, 41, 943

145 : 1, 5, 29, 145

851 : 1, 23, 37, 851

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 943,145,851,638, is 1.

Now, the common factors can be found like this.

943:23x 41

145:5x 29

851:23x 37

638:2x 11x 29

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

23x 29 = 667

Therefore, the value for common factors is 667.

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 = 74238627430/(1x667)

LCM = 74238627430/667

LCM = 111302290

Thus, we can understand that the LCM of 943,145,851,638 is 111302290.
