Given numbers are 138,986,488,481

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

The LCM of 138,986,488,481 is 7984742376.

Find LCM of 138,986,488,481 with Prime Factorization

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

2 x 69 x 493 x 244 x 481 = 7984742376

Therefore, the lowest common multiple of 138,986,488,481 is 7984742376.

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 986 x 488 x 481 = 31938969504

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

986 : 1, 2, 17, 29, 34, 58, 493, 986

488 : 1, 2, 4, 8, 61, 122, 244, 488

481 : 1, 13, 37, 481

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,986,488,481, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

986:2x 17x 29

488:2x 2x 2x 61

481:13x 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 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 = 31938969504/(1x4)

LCM = 31938969504/4

LCM = 7984742376

Thus, we can understand that the LCM of 138,986,488,481 is 7984742376.
