Given numbers are 138,409,926,338,902

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

The LCM of 138,409,926,338,902 is 1991804145474.

Find LCM of 138,409,926,338,902 with Prime Factorization

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

2 x 69 x 409 x 463 x 169 x 451 = 1991804145474

Therefore, the lowest common multiple of 138,409,926,338,902 is 1991804145474.

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 409 x 926 x 338 x 902 = 15934433163792

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

409 : 1, 409

926 : 1, 2, 463, 926

338 : 1, 2, 13, 26, 169, 338

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,409,926,338,902, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

409:409

926:2x 463

338:2x 13x 13

902:2x 11x 41

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 2 = 8

Therefore, the value for common factors is 8.

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 = 15934433163792/(1x8)

LCM = 15934433163792/8

LCM = 1991804145474

Thus, we can understand that the LCM of 138,409,926,338,902 is 1991804145474.
