Given numbers are 638,903,349,935

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

The LCM of 638,903,349,935 is 17090421810.

Find LCM of 638,903,349,935 with Prime Factorization

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

11 x 58 x 903 x 349 x 85 = 17090421810

Therefore, the lowest common multiple of 638,903,349,935 is 17090421810.

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 903 x 349 x 935 = 187994639910

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

903 : 1, 3, 7, 21, 43, 129, 301, 903

349 : 1, 349

935 : 1, 5, 11, 17, 55, 85, 187, 935

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,903,349,935, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

903:3x 7x 43

349:349

935:5x 11x 17

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

11 = 11

Therefore, the value for common factors is 11.

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 = 187994639910/(1x11)

LCM = 187994639910/11

LCM = 17090421810

Thus, we can understand that the LCM of 638,903,349,935 is 17090421810.
