Given numbers are 329,661,647,661

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

The LCM of 329,661,647,661 is 140702443.

Find LCM of 329,661,647,661 with Prime Factorization

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

661 x 329 x 1 x 647 x 1 = 140702443

Therefore, the lowest common multiple of 329,661,647,661 is 140702443.

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.

329 x 661 x 647 x 661 = 93004314823

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.

329 : 1, 7, 47, 329

661 : 1, 661

647 : 1, 647

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 329,661,647,661, is 1.

Now, the common factors can be found like this.

329:7x 47

661:661

647:647

661:661

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

661 = 661

Therefore, the value for common factors is 661.

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 = 93004314823/(1x661)

LCM = 93004314823/661

LCM = 140702443

Thus, we can understand that the LCM of 329,661,647,661 is 140702443.
