Given numbers are 639,799,388,235

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

The LCM of 639,799,388,235 is 990488340.

Find LCM of 639,799,388,235 with Prime Factorization

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

47 x 639 x 17 x 388 x 5 = 990488340

Therefore, the lowest common multiple of 639,799,388,235 is 990488340.

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.

639 x 799 x 388 x 235 = 46552951980

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.

639 : 1, 3, 9, 71, 213, 639

799 : 1, 17, 47, 799

388 : 1, 2, 4, 97, 194, 388

235 : 1, 5, 47, 235

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,799,388,235, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

799:17x 47

388:2x 2x 97

235:5x 47

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

47 = 47

Therefore, the value for common factors is 47.

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 = 46552951980/(1x47)

LCM = 46552951980/47

LCM = 990488340

Thus, we can understand that the LCM of 639,799,388,235 is 990488340.
