Given numbers are 138,428,818,850

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

The LCM of 138,428,818,850 is 5133399900.

Find LCM of 138,428,818,850 with Prime Factorization

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

2 x 69 x 214 x 409 x 425 = 5133399900

Therefore, the lowest common multiple of 138,428,818,850 is 5133399900.

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.

138 x 428 x 818 x 850 = 41067199200

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.

138 : 1, 2, 3, 6, 23, 46, 69, 138

428 : 1, 2, 4, 107, 214, 428

818 : 1, 2, 409, 818

850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,428,818,850, is 2.

Now, the common factors can be found like this.

138:2x 3x 23

428:2x 2x 107

818:2x 409

850:2x 5x 5x 17

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 41067199200/(2x4)

LCM = 41067199200/8

LCM = 5133399900

Thus, we can understand that the LCM of 138,428,818,850 is 5133399900.
