Given numbers are 638,201,781,792,536

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

The LCM of 638,201,781,792,536 is 109258776.

Find LCM of 638,201,781,792,536 with Prime Factorization

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

2 x 2 x 2 x 3 x 11 x 67 x 29 x 1 x 71 x 3 x 1 = 109258776

Therefore, the lowest common multiple of 638,201,781,792,536 is 109258776.

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 201 x 781 x 792 x 536 = 42516523057536

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

201 : 1, 3, 67, 201

781 : 1, 11, 71, 781

792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792

536 : 1, 2, 4, 8, 67, 134, 268, 536

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,201,781,792,536, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

201:3x 67

781:11x 71

792:2x 2x 2x 3x 3x 11

536:2x 2x 2x 67

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 2x 3x 11x 11x 67 = 389136

Therefore, the value for common factors is 389136.

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 = 42516523057536/(1x389136)

LCM = 42516523057536/389136

LCM = 109258776

Thus, we can understand that the LCM of 638,201,781,792,536 is 109258776.
