Given numbers are 397,129,344,661

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

The LCM of 397,129,344,661 is 270814344.

Find LCM of 397,129,344,661 with Prime Factorization

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

43 x 397 x 3 x 8 x 661 = 270814344

Therefore, the lowest common multiple of 397,129,344,661 is 270814344.

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.

397 x 129 x 344 x 661 = 11645016792

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.

397 : 1, 397

129 : 1, 3, 43, 129

344 : 1, 2, 4, 8, 43, 86, 172, 344

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,129,344,661, is 1.

Now, the common factors can be found like this.

397:397

129:3x 43

344:2x 2x 2x 43

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.

43 = 43

Therefore, the value for common factors is 43.

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 = 11645016792/(1x43)

LCM = 11645016792/43

LCM = 270814344

Thus, we can understand that the LCM of 397,129,344,661 is 270814344.
