Given numbers are 387,287,705,473

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

The LCM of 387,287,705,473 is 287113365.

Find LCM of 387,287,705,473 with Prime Factorization

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

3 x 43 x 3 x 287 x 235 x 11 = 287113365

Therefore, the lowest common multiple of 387,287,705,473 is 287113365.

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.

387 x 287 x 705 x 473 = 37037624085

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.

387 : 1, 3, 9, 43, 129, 387

287 : 1, 7, 41, 287

705 : 1, 3, 5, 15, 47, 141, 235, 705

473 : 1, 11, 43, 473

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,287,705,473, is 1.

Now, the common factors can be found like this.

387:3x 3x 43

287:7x 41

705:3x 5x 47

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.

3x 43 = 129

Therefore, the value for common factors is 129.

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 = 37037624085/(1x129)

LCM = 37037624085/129

LCM = 287113365

Thus, we can understand that the LCM of 387,287,705,473 is 287113365.
