Given numbers are 638,889,958,470

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

The LCM of 638,889,958,470 is 63844841830.

Find LCM of 638,889,958,470 with Prime Factorization

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

2 x 319 x 889 x 479 x 235 = 63844841830

Therefore, the lowest common multiple of 638,889,958,470 is 63844841830.

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.

638 x 889 x 958 x 470 = 255379367320

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.

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

889 : 1, 7, 127, 889

958 : 1, 2, 479, 958

470 : 1, 2, 5, 10, 47, 94, 235, 470

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,889,958,470, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

889:7x 127

958:2x 479

470:2x 5x 47

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 = 255379367320/(1x4)

LCM = 255379367320/4

LCM = 63844841830

Thus, we can understand that the LCM of 638,889,958,470 is 63844841830.
