Given numbers are 638,938,364,759,242

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

The LCM of 638,938,364,759,242 is 5904846948.

Find LCM of 638,938,364,759,242 with Prime Factorization

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

2 x 7 x 11 x 29 x 67 x 26 x 69 x 11 = 5904846948

Therefore, the lowest common multiple of 638,938,364,759,242 is 5904846948.

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 938 x 364 x 759 x 242 = 40011242919648

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

938 : 1, 2, 7, 14, 67, 134, 469, 938

364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364

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

242 : 1, 2, 11, 22, 121, 242

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,938,364,759,242, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

938:2x 7x 67

364:2x 2x 7x 13

759:3x 11x 23

242:2x 11x 11

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

2x 2x 2x 7x 11x 11 = 6776

Therefore, the value for common factors is 6776.

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 = 40011242919648/(1x6776)

LCM = 40011242919648/6776

LCM = 5904846948

Thus, we can understand that the LCM of 638,938,364,759,242 is 5904846948.
