Given numbers are 638,759,902,311,407

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

The LCM of 638,759,902,311,407 is 20769007314.

Find LCM of 638,759,902,311,407 with Prime Factorization

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

2 x 11 x 29 x 69 x 41 x 311 x 37 = 20769007314

Therefore, the lowest common multiple of 638,759,902,311,407 is 20769007314.

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 759 x 902 x 311 x 407 = 55287097469868

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

759 : 1, 3, 11, 23, 33, 69, 253, 759

902 : 1, 2, 11, 22, 41, 82, 451, 902

311 : 1, 311

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,759,902,311,407, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

759:3x 11x 23

902:2x 11x 41

311:311

407:11x 37

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

2x 11x 11x 11 = 2662

Therefore, the value for common factors is 2662.

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 = 55287097469868/(1x2662)

LCM = 55287097469868/2662

LCM = 20769007314

Thus, we can understand that the LCM of 638,759,902,311,407 is 20769007314.
