Given numbers are 142,244,302,642

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

The LCM of 142,244,302,642 is 839711604.

Find LCM of 142,244,302,642 with Prime Factorization

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

2 x 71 x 122 x 151 x 321 = 839711604

Therefore, the lowest common multiple of 142,244,302,642 is 839711604.

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 302 x 642 = 6717692832

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

302 : 1, 2, 151, 302

642 : 1, 2, 3, 6, 107, 214, 321, 642

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,244,302,642, is 2.

Now, the common factors can be found like this.

142:2x 71

244:2x 2x 61

302:2x 151

642:2x 3x 107

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 = 6717692832/(2x4)

LCM = 6717692832/8

LCM = 839711604

Thus, we can understand that the LCM of 142,244,302,642 is 839711604.
