Given numbers are 639,142,293,241

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

The LCM of 639,142,293,241 is 90243414.

Find LCM of 639,142,293,241 with Prime Factorization

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

71 x 9 x 2 x 293 x 241 = 90243414

Therefore, the lowest common multiple of 639,142,293,241 is 90243414.

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.

639 x 142 x 293 x 241 = 6407282394

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.

639 : 1, 3, 9, 71, 213, 639

142 : 1, 2, 71, 142

293 : 1, 293

241 : 1, 241

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,142,293,241, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

142:2x 71

293:293

241:241

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

71 = 71

Therefore, the value for common factors is 71.

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 = 6407282394/(1x71)

LCM = 6407282394/71

LCM = 90243414

Thus, we can understand that the LCM of 639,142,293,241 is 90243414.
