Given numbers are 142,244,370,394

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

The LCM of 142,244,370,394 is 631373180.

Find LCM of 142,244,370,394 with Prime Factorization

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

2 x 71 x 122 x 185 x 197 = 631373180

Therefore, the lowest common multiple of 142,244,370,394 is 631373180.

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.

142 x 244 x 370 x 394 = 5050985440

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.

142 : 1, 2, 71, 142

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

370 : 1, 2, 5, 10, 37, 74, 185, 370

394 : 1, 2, 197, 394

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,244,370,394, is 2.

Now, the common factors can be found like this.

142:2x 71

244:2x 2x 61

370:2x 5x 37

394:2x 197

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 = 5050985440/(2x4)

LCM = 5050985440/8

LCM = 631373180

Thus, we can understand that the LCM of 142,244,370,394 is 631373180.
