Given numbers are 355,442,643,221,473

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

The LCM of 355,442,643,221,473 is 47722450490.

Find LCM of 355,442,643,221,473 with Prime Factorization

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

13 x 17 x 355 x 2 x 643 x 1 x 473 = 47722450490

Therefore, the lowest common multiple of 355,442,643,221,473 is 47722450490.

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.

355 x 442 x 643 x 221 x 473 = 10546661558290

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.

355 : 1, 5, 71, 355

442 : 1, 2, 13, 17, 26, 34, 221, 442

643 : 1, 643

221 : 1, 13, 17, 221

473 : 1, 11, 43, 473

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,442,643,221,473, is 1.

Now, the common factors can be found like this.

355:5x 71

442:2x 13x 17

643:643

221:13x 17

473:11x 43

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

13x 17 = 221

Therefore, the value for common factors is 221.

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 = 10546661558290/(1x221)

LCM = 10546661558290/221

LCM = 47722450490

Thus, we can understand that the LCM of 355,442,643,221,473 is 47722450490.
