Given numbers are 541,669,669,643

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

The LCM of 541,669,669,643 is 232720347.

Find LCM of 541,669,669,643 with Prime Factorization

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

3 x 223 x 541 x 1 x 1 x 643 = 232720347

Therefore, the lowest common multiple of 541,669,669,643 is 232720347.

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.

541 x 669 x 669 x 643 = 155689912143

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.

541 : 1, 541

669 : 1, 3, 223, 669

669 : 1, 3, 223, 669

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 541,669,669,643, is 1.

Now, the common factors can be found like this.

541:541

669:3x 223

669:3x 223

643:643

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

3x 223 = 669

Therefore, the value for common factors is 669.

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 = 155689912143/(1x669)

LCM = 155689912143/669

LCM = 232720347

Thus, we can understand that the LCM of 541,669,669,643 is 232720347.
