Given numbers are 338,430,654,142

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

The LCM of 338,430,654,142 is 1687179390.

Find LCM of 338,430,654,142 with Prime Factorization

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

2 x 169 x 215 x 327 x 71 = 1687179390

Therefore, the lowest common multiple of 338,430,654,142 is 1687179390.

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.

338 x 430 x 654 x 142 = 13497435120

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.

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

430 : 1, 2, 5, 10, 43, 86, 215, 430

654 : 1, 2, 3, 6, 109, 218, 327, 654

142 : 1, 2, 71, 142

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,430,654,142, is 2.

Now, the common factors can be found like this.

338:2x 13x 13

430:2x 5x 43

654:2x 3x 109

142:2x 71

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 = 13497435120/(2x4)

LCM = 13497435120/8

LCM = 1687179390

Thus, we can understand that the LCM of 338,430,654,142 is 1687179390.
